Orange on Ulota crispa
Edvin Johannesen, 05-01-2019 14:57
Edvin JohannesenThese orange "jelly"-like apothecia grow at the apex of the moss Ulota crispa.  Spores measure 60-70 x 11 microns.  Multiseptate.  Multiguttulate.  Any suggestion?

Re : Orange on Ulota crispa
The collector has sent med these two photos. I see these in the microscope, but apparently not inside asci. I am uncertain whether these are paraphyses or conidia of some sort.

Hello Edvin,


whatever this is - no apothecia.


Oddly enough: there is no Octospora known from Ulota by now (as far as I know).


Best regards, Lothar

Re : Orange on Ulota crispa
Could you please test the asci with Lugol? Are there any paraphyses? And did you see the excipulum?
Edvin Johannesen, 05-01-2019 15:20
Edvin Johannesen
Re : Orange on Ulota crispa
Hi Lothar,

Actually I was in doubt whether to call them apothecia or not. They are rather shapeless.

I also found that there were no ascomycetes known on Ulota in Hansruedis review from 1988. But much has happened since then ...

Thanks.

Re : Orange on Ulota crispa

Sorry, I was too fast - and did not see the foto of the ascus first - and thought the second fotos (the very long spores, which more likely are conidia) would be the spores of the fungus.


So - this could be apothecia. Maybe of a species of Octosporella or something similar.


Best, Lothar

Re : Orange on Ulota crispa
I am beginning to doubt that the spores and ascus I submitted initially, actually belong here. I am struggling to find further asci and spores. What I do see is tufts/bundles of what looks like paraphyses. I doubt they are spores, since they appear to break loose with a hyaline cell at the break-off point.

Here are a few images of these "paraphyses" and a few from "excipulum". Tissue is partially gelatinised. It is very difficult to make clean sections.

No, it's definitely a fungus. I am looking at muscicolous myxomycetes virtually daily. It's interesting to note that this fungus grows in the middle of the apical growth point on virtually every branch of the moss.

I do see the similarity in shape to some Oscillatoria species. However these filiform "spores" are hyaline without any sign of photosynthesising structures. And they clearly belong to the fungus (see latest photos).  Thanks.

Jokes aside - I take your point, Martin. The images you are referring to were taken by the collector and sent to me, but I have assumed that they are the same structures which I observed. In which case the greenish colour is an artifact.

Re : Orange on Ulota crispa
Hello,
I wonder if this collection could be related to Belonium coroniforme (in Zotto's folder under Belonioscyphella here: https://drive.google.com/drive/u/0/folders/0B5SeyOEkxxZhaG11dlBYTDZtREk ). The spore shape and contents and apothecium structure look similar to me, however spore size is different and no septa there. 
Viktorie
Edvin Johannesen, 08-01-2019 10:38
Edvin Johannesen
Re : Orange on Ulota crispa
Very interesting, Viktorie. I think this is the same, or something very close to the fungus displayed in the folder you are referring to. Look at the pictures added on 22. May 2012! Let me quote the comments by Zotto (I assume) in the folder:

"Helotiales, 18.V.2012-2a.jpg" 2012-05-24, on Orthotrichum striatum, leg. Carlos Sánchez. Inoperculate asci are RR, with croziers, eight-spored, up to 200 x 17. Paraphyses and ectal excipulum are also hemiamyloid! Medulla is strongly gelatinized and exudates carotenoids everywhere. There are also carotenoids in paraphyses and ectal excipulum. Spores from scale 46-55 x 5.1-5.6 µm, 7(-13) septate, which germinate or form conidia? (I don't think so). Flesh composition is different, not Belonioscyphella. --- 1) I was wrong, spores only get 6-8 septated. I was confused because in some spores oil contents looked as septa. 2) Hemiamyloid reaction is not restricted to ectal excipulum and paraphyses, it is also present in the medulla. Even some spore walls react blue.3) All the apothecia is more or less gelatinized. This makes it difficult to section. Maybe gel gives the hemiamyloid reaction?4) Again not sure about microconidia on spores. Probably they just only germinate as you think. Maybe I confuse microconidia with plenty of ¿bacteria?5) Some of these ¿bacteria? react blue in IKI.Please see footnotes of the pics attached to understand what I´m talking about.After comparing with your Naeviopsis, it fits very good except for the lack of hemiamyloid reaction.
"Helotiales, 18.V.2012-4k, ectexc.jpg" ectexc fide Raul
"Helotiales, 18.V.2012-4l2, ectexc.jpg" ectexc?"

Regarding Belonium coroniforme, it was described on Orthotrichum. The collector of the present fungus now tells me that is may well be Orthotrichum on which it grows. I don't know mosses well enough to decide.

I will try once again to find ascospores in the material. And maybe will will have its DNA sequenced in the near future.
Edvin Johannesen, 08-01-2019 12:15
Edvin Johannesen
Re : Orange on Ulota crispa
Finally I found an apothecium with a ripe hymenium. The spores I have measured this time are ca. 30-45 x 4-5 µm, asci are ca. 110-140 x 10 µm (all measures in CR in water). Ripe spores germinate at both ends. It seems they are mostly 7-septate. Asci 8-spored. Asci I believe have croziers (?). The photos are taken at 1000x (oil) - scale intervals ca. 1 µm.  There is little doubt in my mind that this is the same fungus as was displayed in Zotto's folder from May 2012.

@Edvin: How about the IKI-reaction of ascus-tips? The one in Zotto's folder reacts strongly hemiamyloid. But Rehm's original description sais: "J-".

Re : Orange on Ulota crispa
I tried to put the second half of the apo in Barals. Unfortunately, I found only a couple of immature asci there.  In those I did not see any IKI reaction, but I am not quite convinced. I am a bit hesitant to spend more apothecia.

Re : Orange on Ulota crispa
So I tried to treat with Baral's medium after CR staining. I got some dark red staining in the ascus tip - in some asci diffuse staining, in some asci a narrow pore staining. Since this staining is not there in CR, I assume it is caused by the addition of IKI (?). I leave it to you experts to interpret.

Re : Orange on Ulota crispa
I can only confirm Viktorie's great idea.  I must apologize not to have mentioned Raul Tena as the author of the photos in the text to this fungus.

For the iodine reaction I think one ascus shows the red very well. Interesting would be to try a KOH-pretreatment. The Congo might disturb a bit the test, mut mot much. After adding 2-5% KOH for some seconds and removal of the KOH with water, add again IKI or MLZ and, apart from the blue apical ring you should see a distinctly light blue hymenium as figured by Raul.

Indeed Rehm's remark of inamyloid asci is surprising because he used IKI, not MLZ, which was not in use at that time, and he described the red (hemiamyloid) reaction as violet when he saw it.

A DNA result would be great of course.

Zotto
Edvin Johannesen, 08-01-2019 13:47
Edvin Johannesen
Re : Orange on Ulota crispa
Thanks for the tip, Zotto. I will re-wet the material once more to ensure there is ample material to spend one more for the iodine reaction, based on your recommendations.  Luckily, mature apothecia are not crucial for DNA studies.

You can also try via my homepage, but maybe the same will happen.

www.in-vivo-veritas.de

Martin, the type label is interesting, I am surprised to see large globose oil drops which look like in a living spore! In Raul's  photos I only see many small droplets. These large drops Rehm did not mention, instead he described the dead spores with their obvious septa.

Edvin Johannesen, 08-01-2019 18:04
Edvin Johannesen
Re : Orange on Ulota crispa
Zotto, your method worked :-). Here is the result after pre-treatment with 5% KOH, then washing with water, and finally adding IKI (Baral'ische lösung). I see no staining other than in the ascus apical appratus.

Good! Well, I do not know these fungi personally, and I can only make suggestions. Why Raul got this reaction with the same method I do not know.

But now I realized in your living spore the large drops just as Rehm had drawn them!
Edvin Johannesen, 08-01-2019 18:36
Edvin Johannesen
Re : Orange on Ulota crispa
Yes. In some of spores it seems like the large drops press against the septa and distorts (bends) them.
Hans-Otto Baral, 08-01-2019 18:44
Hans-Otto Baral
Re : Orange on Ulota crispa
Surely not the LBs. You perhaps mean bulging of the septa caused by differences in turgor between adjacent cells. Usually one of the two adjacent cells is dead and turgorless when such bulging (convex septum) occurs. The first spor pic  shows a living spore with straight septa.
Martin Bemmann, 08-01-2019 18:59

Re : Orange on Ulota crispa
I wonder if the second drawing of a dead spore is by Rehm. Since when does millimeter paper with orange lines exist? In 1905? There is also a revision slip by Arendholz from 1982. Maybe it is drawn by him?

Hi,

I have a collection of Belonium coroniforme from Slovakian mountains. It was growing in a large group, but unfortunately it was sterile. We have LSU and TEF obtained from this collection + a few more else provided by colleagues /always from Orthotrichum/. So, if someone will sequence Edvin´s collection, we can compare our data.

Hm, I am inclined to assume that millimeter paper was in use very long ago. In any case, I cannot imagine that someone else than Rehm glued this drawing between the other spore and the text. Why did he leave this space? Maybe the dead spore was drawn later by him, and the living one was first drawn as a sketch on another paper.

Belonioscyphella hypnorum is very difficult to put in a family. There is ITS, LSU and Ef1 in GenBank by Z. Egertova. Zuzana, did you compare your LSU? What is next in Blast?

Rehm was certainly not aware of hemiamyloidity. He expected a blue reaction, if any. Thus it was J- for him. Where did he speak of a violet reaction?

Re : Orange on Ulota crispa
The bryo-expertise has now confirmed that the current specimen is growing on Ulota crispa s. lat. (the Ulota crispa complex comprises U. crispa s. str., U. crispula, and U. intermedia). U. crispa was originally described as Orthotrichum crispum, and transferred to Ulota in 1818. The collector of the holotypus specimen was a bryologist and it is likely that it was growing on Orthtrichum s. str., which would imply that the fungus can grow on both Orthotrichum and Ulota spp.
