in other words

<div>Hello forum,</div> <div>this is a tentative translation in English of Michel's words.</div> I speak on behalf of his closest friends to inform you of the sudden death, at his home, of Christian Lechat. Yes, our friend Christian ! The creator of this magnificent Ascofrance forum which has become, as he wished, an essential link between the members of the mycological community passionate about the study of ascomycetes. A community without borders, animated by the sharing of knowledge as much as by mutual respect. Christian leaves us at the top of his art in the study of Hypocreales, especially Nectriaceae and Bionectriaceae, a field in which he handed on to us dozens of new species, many of which were collected in the Lesser Antilles and French Guiana. Christian was soon to celebrate his 70th birthday, he had many publications in progress and devoted himself entirely to this immeasurable task, most often with Jacques Fournier and Amy Rosman, among other faithful and numerous friends. His expertise, recognized by the international community, earned him the Gordon and Tina Wasson Award from the prestigious Mycological Society of America in 2020. Christian was also an actor at the local level where he chaired for nearly twenty years the Mycological Society of the Massif d'Argenson within which we organized together the fabulous meetings of Mellasco. Ascofrance must remain this place of meetings, sharing and friendship that Christian created. We will see to it. Michel

Hypomyces leotiicola

Hypomyces leotiarum Fayod 1885 is the Sepedonium (S. leotiarum) anamorph of H. leotiicola Rogerson and Samuels 1985, According to the latest ICN there is ony one name for each fungus. Hence H. leotiicola iand Sepedonium leotiarum iare synonyms. The names are still listed separately in both Index fungorum and Mycobank but one name must be chosen according to the rules.

Cancellation of Melleasco

Dear Ascofrance community, It is disappointing news that Melleasco has been cancelled this year. I sincerely hope that it will be possible see it back on the programme in 2015. For those within the Ascofrance community who would like to meet up with others to look at Ascomycetes, we in the UK have already organised a week in May to study these organisms. This is part of the British Mycological Society programme see: <a href="http://www.britmycolsoc.org.uk/mycology/field-meetings/programme/2014-stainborough/">http://www.britmycolsoc.org.uk/mycology/field-meetings/programme/2014-stainborough/</a> we have the capacity to include other colleagues from Europe. We would be happy to offer our event as an alternative to the one in Mellasco and we would welcome your participation. Some notes on the event: We will be based in South Yorkshire at Wentworth castle. <a href="http://www.northern.ac.uk/content/?id=11%20">http://www.northern.ac.uk/content/?id=11</a> This is a college for adults who did not succeed whilst at school. We will be using rooms within the college as workroom (lab) and staying in single, double or twin ensuite rooms on site. We will eat in the refectory with the students. Self service basic food. (This is to keep the costs down.) There is a Bar open in the evening. We will visit different sites each day, sharing car transport and taking with us a simple individual picnic snack of sandwich fruit drink and biscuit. Return at 2-3 pm to work on specimens. We have two experienced UK experts with us to help individuals if they are needed. Dr Paul Cannon (RBG Kew and formerly CABI) will assist with the identification of the pyrenomycetes and Chris Yeates will assist with other groups. (Please note it appears that this is a pyrenomycete workshop on our web page, this is not the case.) At the end of the week Chris Yeates will run a beginners course on ascomycete basics and hopes to cover most orders and cover basic handling and identification techniques. This will be in a separate area as it is a formal workshop specifically aimed at beginners and for those who wish to improve their skills. The main meeting will continue to run alongside in the main room. Most of the time will be spent working on material collected, exchanging help with an occasional presentation of a collection found that is interesting (projection microscope)or a powerpoint on a topic; though this is kept to the minimum as people value the time spending on specimens and sharing knowledge. The vicinity is varied,we have some interesting sites to visit, in May we expect it to be warming up and can be good for ascos. We have moorland, industrial sites, broadleaved woodland, alder carrs, willow carrs, Conifer plantation and sandy areas all nearby for collecting. We are on coal measures and shale but within 10 miles to the east we have magnesium limestone and sands; to the west we have carboniferous limestone's and millstone grits. Nearby airports are at Manchester, Leeds, East midlands but this limits equipment (you may have seen my basic stuff which I had put into my suitcase at Someido) However the BMS has 6 microscopes 3 compound and 3 stereo which would be available for use to borrow during the event. For those who have not visited UK, one can drive up from the channel on main motorway roads but as our country is smaller and the population excessive these roads can be busy. Booking forms are at the British Mycological Site link or available from me at the following email address <a href="http://mce_host/forum/foraymanager@tiscali.co.uk.%20">foraymanager@tiscali.co.uk.</a> I can also supply further information. I need to confirm final numbers with the college in early March when I collect final payment. Please email me first to see if places remain before booking. I hope to welcome you to Yorkshire. amites Caroline Hobart British Mycological Society foray manager I'm grateful to Christian Lechat for allowing me to post this

on Casuarina from the Bahamas

Hi all, On a recent visit to the Bahamas, I had a layover at the airport at Nassau where I found these interesting hysterothecia growing on needles of Casuarina. They are quite small, barely reaching .5mm at the longest. Thin walled, elongated, black with a slit along the apex. Asci subglobose, bitunicate with nipple shaped protuberance of ascus contents at the apex. 20.5-24.2 x 12.6-13.9µm Spores are hyaline didymospores– 1-septate, constricted at the septa, upper cell larger than lower, rounded ends, one oil droplet for each cell. 8-10.3 x 3.7-5µm. Can anyone help me identify it? Many thanks in advance. Ethan

Ascofrance needs your help

Dear colleagues Ascofrance was founded in 2003 and since this time, hundreds of persons fascinated by Ascomycota contributed to build the biggest illustrated data base of Ascomycetes available on the Internet. Ascofrance is a totally free and interactive site, it lives and evolves thanks to all those who participate. More than 1500 pages are consulted every day on www.ascofrance.fr. The site Ascofrance is free of advertising and I do wish to keep it that way, but the needs in terms of servers, bandwidth as well as maintenance are important and the work of developers has a cost which is difficult to me to bear alone. Ascofrance is in need of your help to continue and develop, your donations will contribute to assure its viability. To make a donation, please visit the homepage Christian Lechat. Ascofrance is your web site, it is thanks to you that it exists! Thank you for your support

Chlorosplenium Question

Hello AscoFrance, I write again on behalf of Mushroom Observer, which is always in great need of more ascomycete expertise, and always grateful for what expertise it has already received. The latest debate is here: http://mushroomobserver.org/253206 Michael Kuo, an American amateur and creator of the website MushroomExpert.com, describes Chlorosplenium chlora and C. hypochlora as being macroscopically indistinguishable from one another. The descriptions of each species in Dixon, J.R. 1974. Chlorosplenium and its segregates. I. Introduction and the genus Chlorosplenium. Mycotaxon. 1(2):65-104 (http://www.mykoweb.com/systematics/journals/Mycotaxon/Mycotaxon%20v001n2.pdf) do contain some differences, but in the notes for C. hypochlora, that species is said to only differ "on drying and in ascus and spore characters." Are the two species in fact macroscoically indistinguishable? Are their distributions/seasons/substrates separate or overlapping? Many thanks in advance, -Danny

hemiamyloid Calycina from Portugal, on Quercus ilex-acorns

... collected at 11.01.2018 in a macchia near Sao Bras de Alportel (Algarve). The hemiamyloid asci are striking. I found only few free spores, in the asci they were not yet septate as far as I can say. I found this thread: <a href="10525/calycina">http://www.ascofrance.com/forum/10525/calycina</a> Are there new insights and - I am an optimist - can perhaps a name be assigned to my specimen?

Sporomega/Colpoma on Cistus

Hi again What about this Sporomega/Colpoma growing on dead wood of Cistus ladanifer lying on the ground at the SW Spain? The ascospores are 1-septate with a gel seath and an apical globule. Paraphyses with conspicuous Vbs stained blue by Cresyl blue. No yellow KOH reaction or only greenish on the dark, marginal, elements. This collection agrees with Guy Garcia's GG 04040402 and GG 05041001 from 2004 and 2005 on Calluna and Castanaea wood. But my spores are only 1-septate (not 3-septate) and lacks de yellow KOH reaction (saids 'as some Mollisia species'). Do you now some news on this fungus? Thanks again

Mycologia Montenegrina XX

Dear colleagues, you all may remember the call for papers on AscoFrance from 4.III.2016 (http://www.ascofrance.fr/search_forum/41304) regarding Mycologia Montenegrina vol. XX (electronic version, pdf), which was finally published in July 2019 (see http://www.ascofrance.fr/search_forum/59501). A printed version of this volume was announced by the end of winter at the latest. Numerous adverse circumstances and finally Covid made this impossible. Now the conditions for the printed version are finally opening. Through personal communication, we got the impression that there is interest in a printed version. You can see information about the works in the attached content. The price of MM vol. XX will be 30 € plus postage costs (10 -12 €). So to get more accurate information about the total number of copies, we need to know which of you wants a hard copy. Some of you have already announced their wish to us, but to get a complete overview, we would like to ask you to write us an email and send us your residential address in case you want to buy it. Please email branislav@mycolmonten.org . Please note that we will understand this as a binding order. Best regards, Branislav Perić and Hans-Otto Baral

Hyalopeziza on a Betula leaf

Hello forum. last year I found a Hyalopeziza on Betula leaf, which was determined H. cf. tianschanica by Seppo. Now I found something similar, but not quite. The fruitbodies are about 0,1 mm wide, The spores are 5-7x2-3 and have polar droplets, which makes them dufferent from the ealier finding, where I did not see droplets and the spores are wider. The asci are about 20-35x 6-8 and seems IKI-, last year faint IKI blue. The hairs are with lumen, up to 90x3-4 and there are shorter a bit Cistella like hairs, too. The macrophotos were this time a mission impossible ;) Ideas? Marja

Ciboria gallincola

Hello, I have this collection of Ciboria gallincola from Moravia (the Czech Republic). It grew in large amounts on galls of (probably) Andricus quercuscalicis on acorns. Apothecia measure up to 7 mm, are sessile or shortly stipitate, brownish (becoming more yellowish when drying). Ascospores uninucleate, (7.6)8.2-10.4(11.7) × (3.2)3.7-4.2(4.4) µm, Q = (1.8)2-2.7(3.1); n = 100. Me = 9.3 × 4 µm; Qe = 2.3. Asci IKI+, with croziers. Medulla of text. intricata, ectal excipulum of text. globosa. I read at this webpage that the delimitation of Ciboria gallincola vs. C. americana is unclear. Are there some news - did anyone sequenced C. gallincola? Thank you, Zuzana

Cenangiopsis (?) on Sambucus nigra.

Hello everyone I found a collection of months ago (March 23). They only emerged from under the melting snow. Ascomata was old and destroyed so I could not even specify the shape of spores. I kept them alive until today. Only one young Ascomata and a few anamorf have grown, so I could do some photos. Some photos also made of old material. I'm not even sure if this is Ceniengiopsis? Any hints are welcome. Greetings

Chris Yeates

I am letting you know that our good friend and colleague Chris Yeates had a heart attack yesterday and unfortunately the medical team were unable to resuscitate him. This as you can imagine came as a huge shock as I was meeting him tomorrow as he had been assisting in the arrangements for the BMS autumn meeting in East Ayton, Yorkshire, UK. The only consolation is that he was looking forward to the meeting and so passed away anticipating what he enjoyed the most. Chris had remarkable recall for nearly everything – fungi, birds, plants, tv comedy scripts, Captain Beefheart lyrics ... A great friend and a great loss. Chris had been to the doctors a couple of weeks ago and had complained of spells of dizziness which he had put down to the colder weather and his asthma. The 51 participants in scarborough will try to ensure that we work hard this next week to increase the Yorkshire sp list. This was his life passion, his aim and he was well on with this project. I'm sorry to have to pass on this very sad news to you. Carol Hobart

Calycina citrina vs. confluens, ecology

Hello forum, I would like to ask, what is your experience with the ecology of Calycina citrina vs. C. confluens? Do they have any biotop / substrate / wood size preference? I have here a small riparian forest I visit frequently (ash, oak, elm, poplar...) and for several years I keep finding only C. confluens there. So I wonder why not also C. citrina, which is supposed to be at least just as common. Does it prefer bulky beech wood? Thank you. Viktorie

Neotiella?

Hi, Collected on Marchantia polymorpha: Apothecia subsessile, 2,5-3,5 mm diam., disc flat, yellowish orange, outer surface slightly paler, margin with inconspicuous hyaline hairs. Asci operculate, cylindrical-clavate, IKI-, biseriate 8-spored, e.g. 260-285x27-29 µm.Spores ellipsoid to ovoid, (25)31-34x15-18(20) µm, smooth, hyaline, guttulate, most probably with 1-2 large LBs but disturbed by frost. Several misshapen spores due to frost.Paraphyses 4 µm diam., branched, tip clavate and 9-12(15) µm diam., with pale orange granular content.Ectal excipulum of thick-walled, hyaline textura globulosa-angularis, covered with hyaline, thick-walled hairs, 0-3-septate, 65-135x13 µm. This is probably a Neottiella but I do not know any species with such large spores. Any help is welcome. Bernard

Coelomycete with muriform conidia on bud scales of Abies balsamea

<div>Hello everyone,</div> <div>I have been finding this fungus every year for more than 10 years and have never found a name for it. In my files I have called it Camarosporium sp., but that is clearly incorrect.</div> The fungus produces conidiomata on the previous season's bud scales of Abies balsamea. It is very common on older trees along the coast of the Bay of Fundy in New Brunswick. It is mature in May-June but can be found as early as January. The conidiogenous system is hyphal and fills the centrum as a loose tangled mass. The conidiogenous cells are produced on this system and appear to be phialides. The conidia are ovoid, brown and muriform. Germination on DPYA is by continuous budding and never develops a hyphal colony. Is anyone here familiar with this fungus? David

Hymenoscyphus on eucalyptus wood

Hello all, I am having trouble getting to an ID with this species, it is on old eucalyptus wood, sometimes in large numbers and heaped up. Can I please get some assistance. Apothecia are flat with only a small stipe and folds on the underneath surface. Asci: 165-185 x 10-14um, with crosier's and Lugol's +ve for the pore walls Spores: in water: hyaline, multiguttulate with a globose central nucleus, no septate spores seen. Sizes: 27.8 - 39.9 x 5.7 - 6.9um Paraphyces: extending just past asci, filiform with only a few guttules I hope someone can guide me. many thanks Pete

Orbilia/Hyalorbilia on "pyrenomycete"

<div>Hi!</div> <div>This tiny (0.2-0.3 mm), orange one is growing on a stromatic sordariomycete (overgrown by something alike Echinosphaeria) on Salix caprea. I have no ID on the sordario yet. Southern Norway in humid ravine.</div> <div>The Orbilia/Hyalorbilia has broadly ellipsoid spores with one distinct SB at each pole. Measure ca. 2.5-3 x 5 micr. Spores appear more subglobose in water and more ellipsoid with slightly pointed ends in CB (see photos). Dead asci (I think) do not look truncate. Paraphyses broadly cylindrical.</div> <div>Suggestions based on this limited information?</div>

Cercophora?

Hi all, I do have here a fragment of a branch of Sorbus aucuparia, decorticated and with white rot, lying on the ground in a moist environment at about 1050 m height. I recorded Lasiosphaeria ovina, Hyalorbilia inflatula and a Hypoxylon (maybe cohaerens). Between the apothecia of the Hyalorbilia I saw another fungus whose conspicious spores were present in the slides of the Hyalorbilia as well. My guess is a Cercophora. But isn't this a coprophilous genus? Mature spores seem to have an olive-green sporebody. Here are some pictures: Best regards Martin

Need fresh specimens of Ophiognomonia melanostyla

Dear avid microfungus collectors, We are working on the phylogeny of the Diaporthales especially the Gnomoniaceae. We have two isolates of the type species of Ophiognomonia, namely O. melanostyla, but they are slightly different. Thus we would like additional fresh collections of this species so that we can make isolations and sequence it. It occurs in spring on the undersurface of overwintered leaves of Tilia. The black perithecia are partially immersed and it has a very long beak. The ascospores are long, thin, 37-43 x 1.5 2 um. If you find this species and are willing to send it to us, please make an air-dried specimen wrapped in paper and send it to me as an herbarium specimen. Thank you!

Lachnum rhytismatis - confirmation

Bonjour tous I collected this on a previous year's leaf of Quercus. The 'crystal balls' on the rather thin-walled verruculose hairs, and spore size and shape point to Lachnum rhytismatis. Croziers were present, but not very easy to find. Although it has been reported on Quercus a few times in the UK (and Peter Thompson has had it on the 'Quercus-substitute' Castanea sativa) I would welcome confirmation, just in case I have missed something obvious.

Fungi of Carpathians

Dear friends. Yesterday evening I returned from a two-week expedition to the Natural Reserves and National Parks of the Ukrainian Carpathians. At this time there is very wet and cool, so a lot of diverse discomycetes presented. I've never seen such an abundance of them - every collected piece of substrate was covered with fruit-bodies! Every day I thought about how it would be nice if you were there also. I plan to visit Carpathians regularly, so if someone wants to join the trip - you're welcome. To share with you the first impressions from the trip, I spread hastily made a selection of photos of some the most common species. Friendly, Alex.

Leptotrochila ranunculi query

Bonsoir tous while putting together the 'fungus portrait' below I checked to see what the current name was; I was extremely surprised to see that Species Fungorum now has Dothidea ranunculi Fr. as the current name - http://www.speciesfungorum.org/Names/SynSpecies.asp?RecordID=159634? This seems crazy, after all the description for the family in Cannon & Kirk's Families of the Fungi (2008): "Dothideaceae Dothideales: Ascomycota Stromata multiloculate, immersed or erumpent, usually pulvinate or crustose; black, thick-walled, opening by an apical, usually lysigenous pore. Interascal tissue lacking. Asci saccate or clavate, fissi-tunicate. Ascospores small, hyaline or brown, transversely septate." scarcely fits this fungus. I fully appreciate that Species Fungorum is not free of inconsistencies (I have had to point out clear errors to Paul Kirk before, and they have been corrected). Nor is it always up-to-date with the latest studies (its treatment of the Peronosporales, for example is very unreliable). Does anyone have any idea where this strange taxonomic decision has come from? Cordialement Chris

Pinkish on Pteridium

Hello, these pinkish ones are up to 0,5 mm wide. The spores are about 6-8x2-3 and contain two guttules. The asci are about 40-50x6-8, propably IKI-. The paraphyses are about 3 micrometers wide, have a septa and the upper part seems glassy. The glassy part seems to become less obvious with KOH and the guttules vanish from spores. Any ideas? Marja

Cejpia versus Coronellaria

Bonjour, After a late discovery of a nice collection of Cejpia hystrix, I have just read the taxonomic demonstration which lead to the combination Cejpia hystrix (De Not.) Baral . (BARAL H.-O. 1994. Comments on "Outline of the ascomycetes - 1993". - Systema Ascomycetum 13: xx-xx. ) This text was concluded by ''Therefore, the best solution appears to adopt the genus Cejpia for the single species B. hystrix and to abandon the use of the ambiguously applied name Belonium. A thorough study of the Hysteropezizella-complex on living material is necessary to clarify the relation between Cejpia and Coronellaria.'' I wonder whether this relation has now been clarified ? I can see in the Syllabus Ascomycota its placement in the Hysteropezizella lineage whithin the supra Mollisiaceae lineage . Amitiés Michel

Pseudoaleuria?

Hi. Only one small sporocarps (max. 4 mm in diameter) growing on moist soil in the middle of a forest road. On the margins of the sporocarp, there is no hair at all. Only in some places can you observe flocs built of hyphae of unspecified form. Smooth spores, surrounded by a sort of sheath (Tricharina type). Paraphyses without content, septic, tops sometimes slightly widened and slightly curved. No reaction to Lugol and KOH. Any ideas? Best regards. Mirek

Nectriaceae on bark of Banksia

Bon soir, on a dry branch of Banksia grandis in SW-Australia grows on the bark (peridermis) among the hairy felt a nice Nectriaceae which was at first sight taken for an Orbilia. It is characterized by rather large spores. The orange peridium turns deep pink in KOH and does not seem to have a perceptible ostiole. Any idea? I have not tried any key. Sp. *29-31 x 9.5-10.3 µm, smooth, hyaline. Many spores still alive 13 months after collection. There is also a polysporous Nitschkia (?broomeana) on this branch. Zotto

Scutellinia cf. balansae from Ethopia

Dear all, reviewing my collections from Ethiopia, we also came across some Scutellinia collections. And aready the first one poses problems to us. Spores have an ornamentation a bit comperable to S. scutellata, by confluent warts and plaques of different shape, but is coarser and higher as in S. scutellata. Hairs at the margin multifurcate and very long, up to 1600 (-2000 µm), whereas on the flanks they are remarkably shorter and only up to 150-200 µm. Attention: the measures for hair width has to be taken x2,5 (values were in 400x magnification ...) See attached fotos and scetch (drawing by Sylvie). It would be nice to have an opinion from the experts :-) all the best and a happy New Year to you, Andreas and Sylvie

Xerotolerant Orbilia on Malus

Salut à tous, I found this inconspicous Orbilia on Malus x scheideckeri in the South of England that I'd like some help with. The branch was dead, still attached and 6 ft from the ground. 51.093°N 0.1787°W, 96m above sea level Unfortunately I have no material left, but I visit the site often so I have a fair chance of recollection. Apothecia to about 0.8mm Ascospores 4.2 - 5 x 2 - 2.6, smooth, C-shaped, with a large tearshaped-globose SB and sometimes a few smaller ones. Although easy to see, I found the spores almost impossible to photograph - I hope they can be seen on the composite image, but if not I can provide a crop or illustration.... I've used one of Zotto's old keys, which leads me to O.vibrioides (I think! - I don't have much experience using keys to Orbilia). The spore size matches well but I can't find any further information on this species. Have I got it right? Amitiés, Nick

Propolis sp. on Pinus sylvestris

Hello, I found and collected this propoloid ascomycete scarcely growing on the bark of a living tree (Pinus sylvestris) on the 12th of December, this year. It was found in the same area as my previous post (Fagerfjell, municipality of Flesberg, Buskerud county), but on a different locality. This locality is an open, old, pine dominated forest about 610 m.a.s.l. The ascospores are cylindrical to ellipsoid and are filled with small guttules. 19,2-27,2 x 11,2-14,4 µm Me= 21,9 x 12,31 µm The spore wall is about 0,96-1,5 µm (living) and 1,7-2,8 µm (dead) The asci are about 126-147 x 18 µm (dead) The spores were measured in the living state, but I was unable to obtain a spore print. The large variation in the spore measurements may be due to some of the spores being partially immature. All measurements were taken from fresh material in water. Although the spores are a bit small I believe that this resembles Propolis leonis quite well. However, that species has primarily been recorded in areas close to the coast. Could this be the right species, and is anyone aware of P. leonis or a similar species being recorded from submontane regions inland? Thank you in advance and best regards, Hulda

Medusa head fungus - Yellow penicillate conidiophores with snake-like long paraphysis

Hi, I found an interesting ascomycete on the skin of an olive fruit lying on humid ground. According to my interpretation there is a core of profusely branched, yellow, pennillate conidiophores (phialides, etc) overtoped by distinct, broad, cylindrical, septate, very curved paraphysis with the last elemnt slightly swollen. Conidia cylindrical with rounded heads . Some interesting features: 1. Large amounts of conidiospores measuring (6)7-8(9) x 2-3 um, cylindrical and slightly curved with rounded ends 2. Numerous snake-like (curved) paraphyses, 2-3 septate, clavate with very rough (densely verrucose) walls 3. Dense and x2 (or more) branched penicillate conidiophores that are much shorter from the paraphyses 4. Structural cells with deep yellow pigment, more or less subsphericall These fruiting bodies are erupting from the fruit's pulp (not superficial) Spores' size: (6.1) 6.8 - 8.5 (9.1) × (2.2) 2.3 - 2.8 (2.9) µm Q = (2.2) 2.5 - 3.5 (3.9) ; N=27 V = (18) 21 - 33 (38) µm3 Me = 7.7 × 2.5 µm ; Qe = 3 ; Ve = 26 µm3

Trizodia acrobia

Hi All, In April I found what I believe to be Trizodia acrobia in carr woodland in North Wales. This poorly known species would be a new genus to Britain. The only thing is that the ascomata were growing on a waterlogged stick rather than on Sphagnum as in Fungi of Temperate Europe so I was wondering if this is important or if there are other Trizodias out there. Also, I've been told that some lichenologists regard it as a lichen owing to its association with cyanobacteria. I was wondering what the latest state of play is on this. Here is a description of the North Wales material: Trizodia acrobia, Morfa Bychan, North Wales, (VC48, SH547369), 13/4/23. Ascomata consisting of more or less globose, whitish, gelatinous pustules up to c.0.5mm, seated or even immersed in algal scum. Asci: clavate, rather thick walled, 80-98x14-16µm. Ascospores: 14-15x7.5-9 µm, pyriform. Hyphae hyaline, thin to slightly thick-walled, 2-3 wide. Paraphyses somewhat flexuose, slightly swollen to 3-4.5 at apex, sometimes branching, septate. Best wishes, Charles.

Helvella semiobruta or helvellula?

Hi, I found a few specimens of a small Helvella under a small Cistus creticus and close to Pistacia lentiscus at Wardija, Malta. No large trees were in the vicinity. The specimens measure 18-20mm x 20-25mm. Asci were about 280-285µm x 19-21µm, J-ve and biseptate, Paraphyses slightly inflated with 6-7µm at the tips, Spores with large central oil drop 19.3-22.2 x 12.5-14.1µm; Q = 1.40 - 1.67, Mean = 20.8 x 13.4 µm ; Qe = 1.5 This species appears to be associated with Cistus as the specimens were close to the roots. I had found some similar specimens in a different location some time back but there were no Cistus or Pistacia but Olive trees, conifers and Pinus halapensis. Is this specimen H. semiobruta or H. helvellula?

Pyreno on Sticta limbata-2015-08-18

Hi everyone, This is a lichenicolous fungus found growing on the lobes of _Sticta limbata_. Does anyone have any idea about what it could be? I attach a collection of photos with the specimen and the corresponding microscopy. The spores are hialine, simple, guttulate (mostly with one or two drops), many of them have one of the ends plane (truncate), with the following dimensions: (6.9) 8.5 – 11.7 (12.2) x (5.2) 5.6 – 6.9 (7.6) µm Q = (1.1) 1.3 – 1.9 (2.1) ; N = 35 Me = 9.8 × 6.2 µm ; Qe = 1.6 .

Dactylospora sur Buxus sempervirens

Je tente à nouveau ma chance avec un Dactylospora. Récolte sur branche morte de Buxus sempervirens colonisée par Peniophora proxima. GC13051713. Spores 16,3-20,7 x 4,7-6,0 µm, brunes, à 3-7 cloisons transeversales et parfois légèrement muriformes. Asques à paroi épaisse, sommet amyloïde et base dextrinoïde. Paraphyses multicloisonnées, à article terminal clavé, à pigment brun épipariétal. Textura angularis. Excipulum ectal brun foncé, globulosa. Avec la maigre documentation sur ce genre à ma disposition, je vais vers D. frigida. Merci d'avance pour vos avis.

mollisia sur ilex

Bonsoir, Je ne suis pas un habitué du genre mollisia alors il se peut que je vous sollicite pour pas grand chose. Voilà une mollisia trouvée sur mes branches d'Ilex. Micro : asque : IKI bb Spore : 10x14µ , avec la plupart du temps 1 cloison sinon 0 (1 seule spore observée avec 2 = donnée aberrante ?), contenu huileux peu important. Mon problème vient de la potasse. Je n'avais que KOH à 10% et donc je n'ai pu observer qu'une réaction jaune dans une préparation floue (pas doué pour diluer le chimiste de pacotille:@) . D'ici 2 jours je recevrai une potasse moins concentrée, ce sera préférable. Je pensais à Mollisia fusca, vous l'aviez deviné mais comme je n'ai pu observer les hyphes du subiculum j'ai des doutes. Quelqu'un peut-il les lever ? Si c'était M. fusca qui est courante, je ne pense pas que l'habitat (= branche non tombée de houx) le soit. Pour cette raison j'en ferais peut-être une fiche. Merci. Alain

neournula pouchetii

Bonsoir. Le 24/03/2007 j'ai eu la surprise de trouver dans mon jardin cet asco dont les photos sont jointes à ce message. La macro m'a tout de suite fait penser à Neournula pouchetii. La micro a donné: Spores elliptiques 14x24 um lisses dans l'eau mais quelques verrues minuscules et pas évidentes à voir au bleu coton. Asques cylindriques 250x16 um Paraphyses septées 250x4 um La micro me semble donc correcte pour ce taxon. Seul hic : L'habitat... Il n'y a en effet dans mon jardin que des pins sylvestre et des noisetiers. Il n'y a jamais (et j'en suis sûr!) eu ici de cèdres (ce qui est l'habitat normal pour ce champignon). Donc question! Me suis-je trompé? Si non, est-il signalé quelque part que N. pouchetii peut venir ailleurs que sous Cèdres? Merci pour vos réponses. Yannick Mourgues

Small whitish discs with small stalks on dead Quercus twig

Hi everyone, A few days ago I found these small whitish discs with small stalks on a dead Quercus twig. Spores are 1-septate: 9,0-11,0 x 2,5-3,2 µm. See the pictures for some other details. I looked around a bit, but I cannot find a right genus yet. Can anyone point me in the right direction? Thanks in advance. Best regards, William

Literature request - The quest for the missing plate

Dear friends, I am searching plate CCXI that belongs to the following publication: Cavara, F. (1900) - Di una nuova Laboulbeniacea, Rickia Wasmannii, nov. gen. et nov. spec. Revue mycologique vol. 22: 155–156. The text is online available, but the plate seems to be missing. Who can help me? With kind regards, Ron Bronckers

Another fungus on Alpaca dung, again I need help with the determination

Hallo everybody, On a new collection of alpaca dung grows a very small ascomycete. This fungus is much smaller than the one of the former collection, but in some way the spores resembles the ones of the former one on alpaca dung. (which is probably Onygenales, Neven is still examining it) The size of the fungus is about 400µ. It seems, that the spores are in most cases roundish and in a few cases ellipsoid. The paraphyses seem to contain somewhat greenish oil drops. The spores are about 9 µ diameter. On the last photo you can see that the asci are opening with a split. I didn´t see any reaction with Lugol. I need again help with the determination, since I don´t even know the genus. Best regards Christiane

Coprotus disculus?

Greetings Found on Oryctolagus cuniculus dung, apothecia 200 x 170 µm, inamyloid. Asci 67-90 x 14-19 µm. Paraphyses filiform, some curved at apex but I wouldn't descibe them as uncinate. Spores 11.5-14.9 x 7.0-8.6 µm, uniseriate and biseriate. Excipulum textura globulosa-angularis. I've compared this with Coprotus leucopocillum using Doveri as the main reference. The spores are too small for this species; the asci not markedly clavate; and this species also has the spores almost entirely biseriate. I would welcome members' comments. Regards, Chris

Helicoma ambiens?

Un apparence macroscopique en manière de "des poils" de couleur brune - noire. Au microscope des spores hélicoïdales sont observées dans le substrat, multiseptadas (5-9 septos), pigmentées, de 13-20um d'un diamètre. Les "poils" mesurent 200-300 x 5um, ils sont septados, non ramifiés. J'ai supposé que ces "poils" soient les conidioforos de ces spores, et en consultant la bibliographie que j'ai, crois que ce peut être Helicoma ambiens, mais je ne suis pas sûr. Qu'est-ce que vous pensez ?? Un salut et merci beaucoup?. Susana

Crocicreas gramineum

Zotto, i checked this specimen shortly and it similar with your drawings. But you said you are interested in fresh state? (now it is not fresh, but some pictures were done in vital, plus i remember well the place it was collected and may visit it again). The main difference: there are two types of paraphyses: filiform and lanceolate (I don't think that it is underdeveloped, rather two different). Apothecia turbinate, short-stipitate, up to 0,5 mm in diametre, 0,5 mm high, outer surface smooth, brown, edge (collar) lighter, narrow, hymenium grayish, concave; growing in dense groups. Excipulum from textura oblita; asci cylindrical, with croziers, with euamyloid pore, about 50 x 6,5; paraphyses of two types: filiform and lanceolate in one apothecium, filiform scarsely branched, 1,5 mk broad, some enlarged at tips, lanceolate exceeding the asci by 10 mk, up to 3,5 mk in largest part, with 2-3 septa in lower part, may be with thin outbranches; spores ellipsoid, slightly curved, with two big guttules (vital, i suppose it was in water), 10,7 (10-11,8) x 3,3 (3,1-3,5) (N=12). On dead leaves of Milium effususm, coniferous mixed forest, N61,086961 E69,466226, 12.06.2012.

Hypocreopsis rhododendri sites in the Pyrenees

Dear all, I hope to investigate the population genetics of Hypocreopsis rhododendri, and I would therefore like to visit some sites at which the fungus occurs in France. I have the records given in Candoussau, F. (1990) Hypocreopsis rhododendri in southern France. Mycologist, 4(4), 170-171, but I'm struggling to work out exactly where the sites are. I would be very grateful if anyone could give me any information on where exactly this fantastic fungus may be found. Many thanks! Katherine. P.S. The records given in the paper are: Lourdois, Pays de Boretous, 300 m, near a creek, Arudy Ossau Valley, 200 m, near Arudy Thermes de Lurbe St Christau, 200 m, Lannes Pays de Boretous, 600 m, Route de Somport.

Hymenoscyphus macroguttatis

Hi. I found this hymenoscyphus on died branches from Salix caprea, at the edge of a peat bog in 1300m of height in Lozère (48) France. Micro : Asci arrising from croziers, IKI+ strongly blue in Lugol, 110-140x8-10 um Paraphyses septates, filiform with rounded apex, with many refractives guttules (apos becoming red when hurted), width = 2-3 um. Spores cylindrical, not scuttuloid, filled with many small guttules at each side, not septate, 15,4-17,2x5,1-5,9 um Q=2,7-3,2 N=30 With keys I have, I arrive to H. macroguttatis. But I'm not convinced. What do you think about it ??? Yannick Mourgues

Coccomyces dentatus

Bonjour à tous. J'ai une récolte de Coccomyces dentatus qui me pose question en ce sens que j'observe des spores avec 1 voire 2 cloisons. A part cela, tout correspond avec cette espèce. Ma maigre doc sur le genre ne me dit rien sur ces cloisons (en fait il semblerait qu'il n'y en ait pas). Avez-vous des infos là-dessus ? Merci par avance. Yannick

Karstenia on Urtica

Bonsoir tous this rather difficult-to-see asco was collected on a dead stem of Urtica dioica, around an old leaf-node. Asci taking a while (15-20 minutes) to respond to IKI, but then apices blue without KOH. Ascospores fasciculate in the ascus, multi-guttulate, cylindric to narrow clavate, 41.7-57 x 2-2.5µm; up to 9-septate. This looks very close to Zotto's HB 6113, provisionally named Karstenia 'guttulata". Any comments would be very welcome . . . amitiés Chris

Hyalopeziza on a leaf

Hi, these tiny hairy ones are about 0,1 mm wide. The spores are about 6-7x2 and asci about 25-30x5-7. The hairs are glassy, with a lumen and up to 100x3-4 long. Hyalopeziza pygmaea is similar, but the hairs should be shorter. Any other ideas? Marja

Preussia/Sporormiella on grouse dung

I made an abundant collection of some Preussia/Sporormiella on dung of hazel grouze (Tetrastes bonasia) in western Finland. It is somewhere in the neighbourhood of leporina - subtilis but I have difficulties in finding a good match. The spores are (26.7) 27.8 - 34.9 (36.9) × (4.8) 5.0 - 6.3 (6.8) µm, soon breaking up into four part spores. The asci are (108.7) 120.4 - 151.5 (184.7) × (10.1) 11.6 - 14.2 (14.6) µm. Other details in the photos. Ideas, anybody? ------ Update: I was wrong about the substrate - it is black grouse (Tetrao/Lyrurus tetrix).

Stamnaria sp 270717

Good evening Growing on Equisetum arvense, in Bygdim lake, Norway, 1.057 m, together with Roseodiscus rhodoleucus and probably R. equisetinus. I saw "in situ" Roseodiscus, but not this Stamnaria, who grows latter, probably at home. Macro: Cup-shape apos, white-cream to very light orange, semi-transparent, very long stipe, (1052,3) 1159,9 - 2148,4 (2149) × (317,6) 372,1 - 499,2 (521,4) µm; N = 9; Me = 1560,7 × 429,5 µm. Asci cylindrical, 8-spores, uniseriate, with croziers, IKI+, (231) 231,2 - 245,1 (245,7) × (10,6) 10,7 - 11,5 (13,2) µm; N = 7; Me = 238,5 × 11,4 µm. Spores broadly elipsoid, hialine, plenty of small guttules, (16,7) 17,3 - 20,3 (22,2) × (9,9) 10,5 - 12,1 (12,9) µm; Q = (1,4) 1,44 - 1,8 (2,2) ; N = 52; Me = 18,6 × 11,3 µm ; Qe = 1,6. Ectal excipulum with textura porrecta, more prismatica near the margin, but covering with a slim layer of textura gelatinosa. Medullar excipulum and subhymenium more or less with textura intricata. I think the nearest species is S. urceolata, but very pale and with a very broadly elipsoid spores. Thank you for your help.

Octospora?

Salut Ascofrance, I wonder if anyone can help me with this Octospora I found in the South of England on 7/1/2015: Substrate: Growing directly on Orthotrichum sp. (very likely O.affine) on an Ulmus branch 4ft from the ground Ascospores 13.6-15.8 x 11.7 x 13.1 µm, coarsely warted Asci operculate, 8-spored It seems to be a reasonable match for O.affinis, but I have little experience with this group plus I'm aware that similar species exist - Can anyone confirm my suspicions? Amitiés, Nick

Michel Delpont

J'ai le regret d'informer les membres du forum qui connaissaient Michel Delpont qu'il vient de décéder de ce qu'il est convenu d'appeler une longue maladie. C'est pour moi un ami de longue date qui va beaucoup me manquer. Je pense qu'il va manquer aussi à tous ceux qui ont pu apprécier sa gentillesse, sa bonne humeur et son dévouement à partager ses profondes connaissances sur les Ascomycètes coprophiles, pour lesquels il avait depuis longtemps une prédilection. Je suis certain que vous partagez mon émotion. Jacques Fournier I regret to inform those members of the forum who knew Michel Delpont that he has just passed away from what is known as a long illness. He was a long-standing friend who will be sorely missed. I think he will also be missed by all those who came to appreciate his kindness, good humor and dedication to sharing his profound knowledge of coprophilous Ascomycetes, for which he had long had a predilection. I am sure you share my emotion. Jacques Fournier

Podospora perplexens?

Greetings This was found on Pony dung. Perithecium 1mm tall x 0.7mm wide. Hairs around the neck 67-157 x 3.3-3.7 µm, septate. Spores 41.9-49.0 x 21.8-23.2 µm. Me = 45.9 x 22.5 (large sample) Pedicels 34-41 x 5.1-6.4 This seem to fit P. perplexens very well except the spores are a little on the large size according to Ellis & Ellis and Doveri. I don't have Lundqvist and would be grateful if anyone has it available as a download. I welcome comments from those with experience of this genus. Best regards, Chris

Christian n'est plus, Christian has passed away

Bonjour, Je me fais le porte parole de ses amis les plus proches pour vous informer du décès brutal , chez lui, de Christian Lechat . Oui, notre ami Christian ! Le créateur de ce magnifique forum Ascofrance qui est devenu comme il l'a souhaité un lien incontournable entre les membres de la communauté mycologique passionnée par l'étude des ascomycètes. Une communauté sans frontières, animée par le partage des connaissances autant que par le respect mutuel. Christian nous quitte au sommet de son art dans l'étude des hypocréales, notamment nectriacées et bionectriacées, domaine dans lequel il nous lègue des dizaines d'espèces nouvelles dont un bon nombre récoltées aux Petites Antilles et en Guyanne. Christian allait fêter bientôt ses 70 ans, il avait en chantier de très nombreuses publications et se consacrait tout entier à cette incommensurable tâche, conduite le plus souvent avec Jacques Fournier et Amy Rosman, entre autres fidèles et nombreux amis. Son expertise, reconnue par la communauté internationale, lui a valu en 2020 de recevoir avec une immense joie, le prix Gordon et Tina Wasson décerné par la prestigieuse Mycological Society of America. Christian était aussi un acteur au plan local où il a présidé pendant près d une vingtaine d'années la Société mycologique du Massif d'Argenson au sein de laquelle nous avons ensemble organisé les fabuleuses rencontres de Mellasco. Ascofrance doit rester ce lieu de rencontres, de partage et d'amitié que Christian a créé. Nous y veillerons. Michel

Lamprospora sp.

Adio à tous, Adio to all, Une Lamprospora, sur sol, composé de mousses (indet.) et de morceaux d'écorces de pin décoratifs au pied d'une petite haie devant le magasin Leroy Merlin de Pau (64), le 18-01-2013. A Lamprospora, on soil, composed by mixed mosses and pieces of decorative pine bark at the base of a small hedge in front of the store Leroy Merlin, at Pau (F – 64), at 18th january 2013. L'espèce paraît différente de L. miniata que je connais bien du muret de mon jardin, mais je ne suis pas spécialiste du genre. Il semble qu'il y ait moins de mailles, que des verrues sont parfois présentes entre les mailles mais comme L. miniata est une espèce « collective », je ne sais pas trop à quoi se référer... The species seems to be different from L. miniata which I know well from the wall in my garden, but I'm not an expert of the genus. It seems there are fewer stitches, there are warts sometimes present between the stitches, but because L. miniata is a "collective" species, I don't know what thinking... Spores : x 13,5-14,5 µm, parfaitement rondes, avec une guttule excentrée Spores: x 13,5-14,5 µm, perfectly rounded, with an eccentric guttule Merci de votre avis, Thanks for your opinion, Beñat

Trichopeziza ?

<div>Hello all,</div> <div>These were found by my friend recently in Central Park in New York on a branch of what appears to be hardwood. At first they were closed but became cupulate when hydrated. They are sessile, about 1mm in diameter with brown hairs on the outside which become paler near the margin. The hymenium is tan or off-white. Asci 79-87 by 7-9µm, IKI-. Spores cylindrical, somewhat allantoid, hyaline, 13-17 by 3-3.5µm. I wasn't able to take a lot of photos or measurements of hairs or paraphyses etc., but I do still have access to the collection. I was thinking that the microscopic features are similar to T. perrotioides which I found in Zotto's drive. Any thoughts? Many thanks in advance for your comments.</div> <div>Ethan</div>

Nectria sur Buxus

Bonsoir. Me voici en prise avec un Nectria... Trouvé sur Buxus. Issue d'un stroma, perçant l'écorce, avec petite ostiole au sommet de la sphère. Spores hyalines, lisses, 1 cloison, un peu étranglé au niveau de celle-ci, 22,5-27,3x9,4-11,2 um. Q=2,1-2,8 Asques IKI-, spores bisériéees, 100-110x15-20 um. Paroi large : de 90 à 110 um. J'ai regardé dans la base, mais aucun Nectria cité comme venant sur Buxus ne correspond (veuillotiana, cyanostoma, desmazieresii). La maigre littérature que je possède (Dennis) ne m'aide en rien. Pouvez-vous m'aider ? (Et me dire quel bouquin il me faudrait pour travailler correctement ces Nectria). Merci par avance. Yannick

Stigmidium on Lecanora?

Hello all - lichenicolous fungus help needed this time please! Densely clustered very small black perithecia on the apothecia of Lecanora confusa, completely blackening the host apothecia. Spores 1-septate, brown (green-brown to brown in asci) (10) 12-13 (15) x (4)5-7 µm. No host spores to be seen and I did a second section from a different apothecia just to be very certain that it wasn't just Amandinea punctata among the Lecanora. Stigmidium congestum has just been confirmed (by BJC) from L. chlarotera in the same 1km square but the spores of my specimen are wider than the measurement of (2.5)3-4 µm given in the 2010 4th draft Key to Lichenicolous Fungi. Spore width fits better with that given for S. squamariae but that is only included in the key on Lecanora polytropa........ With regards, Jenny

Possibly an undescribed species of Xylaria on olive fruits

I have found an interesting Xylaria growing on fallen drupes of olives which were still immature for a proper morphological examination, however I did sequence it with ITS and LSU and the Lab had suggested that it is closely related to X. palmicola GU322436 and Xylaria sp. ON248209 further adding that it may likely be an undescribed species. I am writing to see if anyone is interested to examine my specimens and sequences for a possible article (I would be happy to step as a co-author). The bad news is that I have to recollect more specimens as I only have three left. Anyone interested feel free to contact me

Bright orange asco between mosses in Belgian dune area

Good evening all, today 14/11/20 we found the following asco in the Doornpanne (dune area) in Koksijde, Belgium. The species grew on seeds (including Betula) deep between mosses (Tortula ruralis). Mushroom height: 4.5mm. Microscopy in H2O unless stated otherwise. Asci: J-; 8-spored; croziers present. Paraphyses: strongly curled; forked; filled with yellow VBs. Spores: with 2 oil drops; strikingly different in size, even within the asci; 9.55x5.09 (N = 15) Anyone have an idea? Regards, William

Stamnaria and related

Hello dear forum, There are two close species which are going to be send to Danny Halewartes soon for detailed study, but i also wanted to show them here. Plus I am sending to him these taxonomically related earlier posted samples: Cyathicula starbaeckii http://www.ascofrance.fr/search_forum/22273 Crocicreas gramineum http://www.ascofrance.fr/search_forum/22254 The first species is close by macro-morphology to Stamnaria persoonii, but has spores more cylindrical, paraphyses of two types and its host is different (E. sylvaticum). Stamnaria sp., Kh-3519, 09.06.2012, 61,070617N 69,468112E, Russia, Khanty-Mansiyskyi avtonomniy okrug, Khanty-Mansiysk, Shapsha village, Coniferous mixed forest. On litter of Equisetum sylvaticum. Apothecia turbinate, stipitate, 0.4-0.6 mm in diameter in mature state, 0.5-0.7 mm height; yellow with whitish collar and translucent stem when alive, becoming light brown on drying; when dry collar closes the hymenium making flat crest; scattered abundantly on branches of Equisetum sylvaticum. Outer layer of apothecium made by gelatinose loosely more or less parallel hyphae, septate, 2-3 mk broad; inner layer of excipulum made from textura prismatica, cells of middle flanks near 30 x 10 mk, shorter to the edge; medulla well developed from wide segmented hyphae, cells near 50 x 7 mk; subhymenium well developed, from intricate hyphae; raising under the hymenium part (collar) has inner layer made from similar to gelatinose narrow hyphae, free upper part of these hyphae covered by warts (outgrowths). Asci cylindrical, ascus development starts from crozier, barely seen in mature asci, with apical thickening, with euamyloid ring of "Calycina-type", †98 x 9 (90-110 x 8-10.5) mk (measured in dead state); paraphyses of two types; first type of lanceolate paraphyses exceed asci for 30-40 mk, segmented in lower part, lanceolate in upper part with quite acute tip, vacuolar content in vital state not observed, †100-130 mk long and 3-6 mk broad in lanceolate part; second type of cylindrical paraphyses more abundant, not exceed the asci, †80-100 mk long and about 2 mk broad, segmented, cylindrical with obtuse tip, rarely branched and scarcely some enlarged in upper segment; spores fusiform, slightly heteropolar, with obtuse ends, guttulate (but character of guttulae not observed in vital state), †22 x 4.2 (19.4-23.6 x 3.8-4.6) mk, n=20, Q=5.3.

A mollisioid aspect but...

Bonjour, I have lately been given a puzzling collection ( unfortunately in poor state) on very rotten wood (Sambucus nigra most probable) covered with mosses. Hymenium looks like a Mollisia but apos are more cupulate and may have sort of dark brown stipes and thick ans also dark ectal . Ectal is of globulose cells, Ascus 90-120 x 9-10 µm, H+ and IKI + (Calycina type) Spores guttulate fusoid , 11-14 x 3 µm Paraphyses cylindrical, hyaline, no VBs , x 2 µm CRB gives a pink-red reaction to hymenium ( Gelatinose tissues ?) I did not test KOH and there is no material left I do not even guess what the genus could be and wonder whether someone could help from the images hereunder ? Thanks anyway . Amitiés. Michel

Une hélotiale sur Sphagnum palustre

Bonjour, Voici une espèce de (?) Hyaloscyphaceae rencontrée plusieurs fois sur des sphaignes. Ici Sphagnum palustre et en mélange avec Bryoscyphus tetrasporus (nom provisoire) : Asques 60-75 x 7-8 , avec crochets, IKI BB Calycina type. P. S. 35-38 Spores (12) 15-20 x 2,8-3 µm , cylindro-clavées , OCI 1-2 de petites guttules plutôt répartiées aux pôles. Non septées. Paraphyses sans vacuoles réfringentes, x 2 µm. Esctal prismatique Poils de marge jusqu'à 120 µm de long, se terminant en pointe, septés, hyalins Ma première hypothèse est une espèce du genre Hyaloscypha mais les spores seraient alors vraiment particulières. La présence non constante d'un subiculum léger m'a aussi fait considérer la famille Arachnopezizaceae mais sopres non septées. Je n'ai pas de certitude sur le caractère infectieux du champignon qui apparait aussi bien sur les mousses bien vertes contrairement au Bryoscyphus tetrasporus récolté sur les mêmes sphaignes. Merci de toute aide possible AmitiésMichel

Hysteriaceous asco with brown didymospores

Hi, I collected this fungus on bark of living Pinus sylvestris – ascospores measure about 25–27 x 10.5–11 µm and become 3-septate when overmature. Most other characters should be shown on the photos but if not I will check the material again, of course. I'd appreciate any ideas! Best wishes, Gernot

Lophiostoma?

Hi, here I have another indetermined pyrenomycet. The substrate is a branch most likely of Crataegus and there were only few ascomata on it. They didn't have compressed necks but because of the microscopical characters I still think it's a Lophiostoma, maybe a species next to L. quadrinucleatum/triseptatum? The quite tiny spores (11,5-15 x 5-6,5 µm) with constantly three septa are remarkable. The asci are 8-spored and bitunicate, paraphysoids are present. The ascomata are smooth and immersed. By the way, is there any good paper about Lophiostoma(taceae) besides Barr's "Notes on Lophiostomataceae"? Best wishes, Gernot ascomata:

Otidea sp.

Good evening, I'd like to ask for your help with this Otidea: Found a few meters from Otidea concinna, on argillaceous ground, only deciduous trees around, 250 m. Apothecia cupulate with a split, about 4 cm wide, hymenium lively ochre-yellow, receptacle more dull ochre. When fresh, it had a sweet (almond-like) smell. When drying, a purplish hue appeared on the receptacular surface for some time. Spores ellipsoid, sometimes a bit inequilateral, 9,3-10,5 (11) × 5,3-5,8 um, Q = 1,7-1,9, with two LBs (sporeprint in water). Paraphyses up to 4 um wide, bent to curved, usually equally wide all along, some a bit enlargened (up to 6 um) and with shallow notch(es). Excipulum with yellow-brown exsudate. In MLZ discolors to reddish-brown, doesn't dissolve, no amber drops nor red particles observed. In KOH turns lemon yellow and dissolves into the medium - this is easily seen even with naked eye, like Mollisia rosae. Mycelium very light brown in exsiccate, hyphae brownish with abundant yellow-brown exsudate. In MLZ stains more golden-brown to reddish-brown without dissolving. KOH reaction same as with excipulum, bright lemon yellow. Unfortunately there's no photo in fresh state, the one here is already drying and a bit darker. The closest match I found was O. flavidobrunneola, but the apothecium colors are perhaps to dark for that species. Is there any other possibility? Thank you in advance. Viktorie

A pyrenomycete (Xylariales) on bark of a fallen Acacia tree

Material from Malta. The immature ascocarps consist of subspherical bodies with a dull olive green velvety indumentum maturing into a dark grey, nebular (cloud-) shaped fruiting body, about 3mm across. It is actually a cluster of perithecia with distinct black ostioles. My attempts to extract or see the asci from the chambers failed, but maybe from this data, the family or genus of the species can be suggested while I try to examine more material. However the spores are quite abundant, black 17-20um long with an interesting sinusoidal or curved germinal slit running diagonally along its length. This expands in 4% KOH and sometimes the perispore becomes lose and peels away. Somewhat it reminds me to Hypoxylon.

Some very swollen asci on a suspected Mollisia sp.

Studying three ascomata from a suspected Mollisia sp., I found that two had a mixture of 'normal' and very swollen, opaque asci. It is difficult to speculate on the cause without more context, and I would appreciate any suggestions. It may be a relatively simple answer like over-maturation, but the appearance is quite different to the other asci (even ones that look vital and turgid to me) and those in the few ascomata of other species I have studied previously. The first ascoma examined was stored for several days prior (in a damp container), but the following two were collected later and examined within hours of collection. Except the missing swollen asci in the second ascomata examined, the characters are similar in the three ascomata, and my current working assumption would be that all are from the same species. Inflated asci: • Contents - a large, relatively opaque group of jumbled circular-looking contents, difficult to interpret these inner contents with any confidence (possibly spores and LBs), some with large LBs around base, sometimes opaque contents fills ascus or transparent areas at the base or apex. • Shape - more broadly cylindrical to ellipsoid, and some look less turgid with the contents at the bottom giving an asymmetric lageniform (bottle-shaped) appearance (particularly in the stored ascomata). • Apex – seems like 'normal', but the contrast causes a more or less pronounced mammiform appearance, also seems harder to see the IKI bb reaction. • Base – again like 'normal', both with croziers.

Desmazierella piceicola Huhtinen & Y. Mäkinen

Hi, finding Desmazierella is not easy. I've been looking for them many years in spring on pinus needles. Now I accidently stumbled across something growing on Picea needles and guessed to have finally found it. Lucky me, the spores were huge, 45-51x9-10, only 4/ascus. Marja

A Melanomma-problem

Hello, in the last few days I have found some Melanomma (I think they are species of Melanomma), but there is one problem : The difference in spore sizes and perithecia features let me think about different species, perhaps different from the common M. pulvis-pyrius. I checked literature but it did not help anyway, i just found some photos of a "M. seminudum" on Zotto's DVD but there are no information about spore size or something. Well here are the descriptions of the perhaps two different species, just to show you and perhaps you can tell me something about it ;) Melanomma No 1 found on decorticated Crataegus-twigs, perithecia not embedded. Spores 18-21x7-8,5 µm. Asci 130-160x10-12 µm. I had not seen any hyphal structures on the outer surface of the perithecia. Melanomma No 2 found on dead, but hanging, corticated Prunus-spinosa-twig, perithecia nearly completely embedded and sometimes (ever?) with a long neck. On the photo you'll see that the perithecia are sometimes clustered in a stroma or whatever. Spores 14-19x5-7µm, thick-walled. Asci 50-80x8-10µm, biseriate and bitunicate. Outer surface with long hyphal structures (?). I just mentioned the differences now, you see the different sizes in spores and asci and especially the perithecia of No 2, which seem to be embedded (unusual for Melanomma-species except M. fuscidulum??). Well, perhaps someone can give some hints for further literature or how to determine these species ;) regards, Kazuya No 1

S/ Scirpus sylvaticus - aspect de Cistella.

Bonjour à tous, Je sèche sur une récolte de minuscules apothécies (la graine de bouleau donne l'échelle) sur feuilles mortes de Scirpus sylvaticus (surtout face inférieure des feuilles), dans une prairie humide ardennaise. Les apothécies sont presque hyalines et courtement poilues, sessiles.

Durella macrospora

Dear all, I recently found a specimen of Durella macrospora which agrees well with the registered sequence. This will be a new report from Japan. To confirm, I would like to see Medardi G. 2004. Documents mycologiques 33: 29-35, which was cited in your article in Willdenowia (47: 271-291). Is there anybody who can provide me with the copy ?

anamorph on resin

... of Picea in the Eifel, about 550 m NN, together with Lachnellula resinaria and Lophium mytilinum. The black "mould" builds spores of about 15-20 (25) µm which show the colour assymetrically. Who can provide me with a name? Best regards, Lothar

Coloration des cloisons

Bonjour, Je pense avoir déterminé Arachnopeziza obtusipila , très conforme à la description donnée par Zotto Baral (CD ROM no 2) mais j'ai des difficultés à mettre en évidence les cloisons des spores. Que pouvez vous me conseiller ? (ai essayé Bleu coton et Rouge congo) Merci. Michel hairaud.

petite leçon

J'aimerais que vous m'aidiez à apprendre quelque chose... Quand on trouve un asco avec des asques remplies de "spores" en grand nombre, on est quelquefois dans une phase de maturité. Peut-on être dans une phase qui donnera des spores secondaires très différentes? oui? A partir de mon champignon, quelle est la première phase et quelle est celle qui approche de la maturité? photo1, photo 2 Je n'ai pas de connaissances fondamentales, et j'ai l'impression que 2 scenarios sont possibles... Merci de votre aide. jean pierre

Bryoscyphus sp? on moss

Hello A small yellow Bryoscyphus sp? on moss, Pleurozium schreberi has been collected in february 2013 by Mila Tanaskovic in Fontainebleau (F). She gave me a part of her collection and it needs to stay three weeks in the bottom of the fridge to see some spores. apothecia are stipitate, 1-2 mm high, diam. 1 (2) mm spores ellipsoid-fusiform, sometime with one septum, OCI low N= 20 ; 12,3-14,8 x 2,8-3,8 Qm= 4 ascus with croziers, 60-70 x10 µm,IKI + excipulum textura epidermoidea? paraphysis filiform, 2 µ wide In Zotto's dvd (pictures and Bernard Declercq's key), I found Helotium ("Bryoscyphus") phascoides that can fit this collection, but the color is white. Have you any idea about it? thanks in advance cheers François

Bryostroma necans

Bonjour, Sur pierre recouvertes de mousses (muscicole/Thuidium/zone humide à 1350m), périthèces sphériques à piriformes avec une petite papille, 0.15 - 0.25 mm de diamètre, asques bituniqués, octosporés, IKI-, 240 - 435 x 35 - 44 µm, spores lisses, hyalines, brunâtres en vieillissant, 4 - 7 cloisons, entourées d'une enveloppe mucilagineuse, 52 - 68 x 13 - 15 µm, paroi brune. Avec ces caractères, je pense qu'il s'agit de Bryostroma necans. Qu'en pensez-vous ? Merci pour votre avis. Elisabeth

Blackish Stippled Fruit Bodies on Corylus avellana

Hello Everyone, I have found what appears to be an effuse layer of fruit bodies expanding across the bark of a dead trunk of Corylus avellana about 50 cm above ground level. Macroscopically, they look like tiny spheres tightly clustered together. Microscopy shows what would appear to be septate hyphae / conidiophores with branches, on which initially hyaline spheres form. As they mature, these clusters of spheres become brown and most seem to contain a refractive guttule. Each tiny sphere is smooth and about 5 um in diameter and most do not separate when prepared for microscopy. I wonder if this effuse layer could be a hyphomycete, but I can not find any species with clusters of smooth conidia resembling these. I have attached photos of the effuse layer and the available microscopic chararacteristics. I wonder if anyone has any ideas about what this might be? Thank You, With Best Wishes, Peter.

Loculomycète parasite sur Velutarina

Bonjour à tous, je manque d'inspiration pour ce champignon, merci pour vos suggestions. Autres photos disponibles si nécéssaire. Amitiés, Jacques JF 06062 Loculoascomycète parasite sur Velutarina rufo-olivacea, Ariège, Rimont, Las Muros, 04 Avril 2006. Ascomes obpyriformes, noirs, ostiolés, à moitié enfouis dans le disque de Velutarina, le col seulement visible, en contact, souvent déformés par pression mutuelle, hauts de 300-350 µm, larges de 200-220 µm. Paroi pseudoparenchymateuse, à cellules isodiamétriques à allongées 8-14 x 5-7.5 µm, à paroi brune épaisse de 1-1.5 µm, garnie intérieurement à l’apex d’une couche de texture indéterminée, hyaline, épaisse de 65-70 µm, entourant le canal ostiolaire. Asques bituniqués, octosporés, clavés, 70-75 x 9-9.5 µm. Pseudoparaphyses cellulaires, septées, de diamètre 1.5 µm, 3 µm à la base, parfois anastomosées. Ascospores 16-18.7 x 6-7.5 µm, bisériées, ellipsoides à extrémités aigues, droites, bicellulaires, euseptées, cloison submédiane, la cellule supérieure plus longue et un peu plus large, légèrement resserrées au niveau de la cloison, se séparant parfois, paroi lisse, jaunâtre. Ressemble par certains points à Phaeodothis winteri (Niessl) Aptroot mais les spores sont différentes. Le manchon apical interne semble être un caractère distinctif. Une récolte identique a été déjà effectuée par Christian en 2003, sur le même hôte.

"Mollisia" subglobosa

Hello everyone You might be interested in this species; it was originally described by Rodway from Tasmania in 1925 but appears to have turned up recently in southern England. Quite an extreme disjunct distribution! The British collections were identified by Brian Spooner. The problem is that it doesn't fit in Mollisia, even in its traditional exceptionally broad sense, but we can't find a suitable home for it. Does anyone have any suggestions, and has anyone happened to collect it elsewhere in Europe? A description and a couple of images are given below; there is more information and pictures at <a href="http://fungi.myspecies.info/all-fungi/mollisia-subglobosa">http://fungi.myspecies.info/all-fungi/mollisia-subglobosa</a>. Click on the Descriptions and Media tabs on that page to see more. All help will be gratefully received Paul Ascomata apothecia, formed singly or in compact clusters of up to 10-12, rather irregular in form but initially circular and discoid, the margins becoming convoluted especially in clustered ascomata, not gelatinized. Disc grey-green, the margin and underside initially pale, the undersurface becoming mid brown with age. Outer wall (ectal excipulum) composed of irregular dark brown angular cells 7-13 µm diam., with an outer layer of hyaline to pale brown cylindrical to clavate cells measuring 8-11 x 3-4 µm. Subhymenial layer composed of poorly defined hyaline hyphal tissue. Interascal tissue of copious unbranched thin-walled paraphyses ca 2 µm diam., sometimes slightly inflated with narrowly clavate tips. Asci 72-87 x 4-5.5 µm, narrowly clavate with a long tapering stalk, the base sometimes forked indicating the presence of croziers, uniformly thin-walled, the apex obtuse to rounded, with an apical ring 2-3 µm diam. and ca 1 µm thick that stains blue in Lugol's iodine, the ascus contents dextrinoid in Melzer's reagent, 8-spored. Ascospores arranged uniseriately, 4.5-5.5 (-6) x 3-3.5 (-4) µm, ellipsoidal or rarely fusiform-ellipsoidal, aseptate, hyaline or very pale yellow in mass, fairly thin-walled, strongly reticulate, the network 0.75-1 µm diam., without a gelatinous sheath or appendages.

Mollisia bleuté sur écorce ?

Bonjour à tous, Voici ce que je pense être un Mollisia mais sans certitude, avec un hyménium d'un beau bleuté et les flancs de l'apothécie noirâtres; a) asques octosporés, IKI-, à crochet à la base b) spores étroitement ellipsoïdes-subfusiformes, à 2-3 microguttules : 5-7x1,2-1,5 c) paraphyses filiformes, fourchues, souvent un peu courbées-enroulées au sommet Bernard

Posible Rhytismatacea

Hola amigos: Hace un par de dias recolecte sobre estrobilo de piña (Pinus pinea) unos pequeños apotecios anaranjados de 2-3 mm. de diametro aproximadamente, pulvinados y erumpentes sobre la capa cortical del estrobilo. He echo la micro y me encuentro con ascas de 150-180 µm., no amiloides, me han parecido octosporicas(me ha sido imposible contar el numero de ascosporas),base aporrhinca, con ascosporas filiformes de dimensiones exageradas de longitud (95-110 µm.) y 2-3 µm. de grosor,y tres o cuatro septos,con uno de los extremos apuntado y el otro extremo achatado -redondeado; parafisis tambien filiformes con el apice engrosado y a veces curvado como en las Otideas. He estado mirando en la bibliografia que dispongo y solo me aproximo a que pudiera pertenecer ( por la forma esporal y la forma de aparecer los apotecios erumpentes en el substrato) al orden Rhytismatales y dentro de el , como posibles géneros Coccomyces o Therrya , pero no encuentro ninguna especie dentro de ellas que me encaje. Aunque muy parecida por el aspecto macro de Coccomyces strobi, el tipo de pino en que aparece no coincide con el de mi recolecta.Respecto al otro genero con esporas filiformes septadas y tan largas, se parece mucho la micro a Therrya pini, pero el aspecto macro , la coloracion no tiene nada que ver por las fotos que he encontrado y las prafisis no presentan como he visto en la base de datos de una recolecta de Enrique Rubio esas incrustaciones mas oscuras en los apices. Solamente macroscopcamengte he podido encontrar Therrya eucalypti, que presenta esa coloracion , pero el habitat tambien es distinto y no he podido comprobar como es su microscopia. Me gustaria saber si alguno teneis alguna idea de cual puede ser la especie en cuestion. Muchas gracias de antemano.
