Bonjour Roland,
sans données mocroscopiques il est impossible de répondre
Amitiés,

C'est vrai qu'il faut plus de données, même si cela ressemble fort au stade imparfait de Ascocoryne sarcoides (qu'il faut appeler Coryne dubia, je crois...)
Alain

yes, Alain, I agree

zotto

Hi Alain and Zotto !

J'aimerais savoir comment identifier une forme imparfaite d'un Coryne ?
Quels sont les éléments à observer ?
Je sais qu'il n'y a ni asques, ni ascospores ni paraphyses. À part peut être les conidiophores et les conidies, quoi d'autres à observer et comment faire ?
De plus, existe-il des clés sur les Coryne ? Pourrais-je en prendre connaissance ?
Je vous remercie de votre support et vous souhaite une bonne année 2009.

Roland

In the attach you can see the anamorphs of A. sarcoides and A cylichnium. The conidia are produced at the tip of the conidiogenous cells (phialides), which are narrow in sarcoides and strongly inflated in solitaria. In earlier times this solitaria anamorph which is very frequent, was believed to be a basidiomycete (Sirobasidum cerasi) because the phialides resemble sterigmata of heterobasidios. The phialides of sarcoides on my drawing you must think with the tips upwards.

I do not remember a key on Coryne.

Here sarcoides
Zotto

here solitaria

Hi Zotto !

Herre is a plate of the Coryne sp.
Are the anamorphes sarcoides and cylichnium the same ?
If I compare with your two figures, I think it' s the first one.
Do you agree with me ?
How can differenciate them ?
And, what is the wright name of the anamorphe in the plate ?

The details :

Date de récolte: 2008 / 11 / 06
Habitat: forêt mixte
Hôte: écorce d'aulne

Conidies cylindro-allantoïdes, biguttulées, hyalines en NaCl iso., inamyloïdes, 4-5 x 1 µm, 4,7 x 1 µm en moyenne (15 spores), Q = 4,7

Thanks you, friendly ! Roland

Hi Roland

yes, I think this is the anamorph of A. sarcoides, and it is called Coryne dubia.

A. cylichnium has no fruitbody-forming anamorph, I never saw one.

I do not understand your conidial measures, the width should be about 1 µm.

Zotto

Zotto, thank you for your answer and figures.
I have made a mistake in measures of spores and I ajust them in my message.
Sorry, they are of course about 1 µm wided.

Roland

Hi Zotto !

Do the Ascocoryne may have a teleomorph and a anamorph on a same structure.
We have a specimen with asques + ascospores and conidiophores + conides.
Am I wright ?
I think it's Ascocoryne sarcoides.
I whait a answer before to place a plate on the forum.

Roland

I think so in sarcoides, that anamorph and teleomorph fruit-bodies may emerge from a common base.
zotto

Hi Zotto !

Here is the plate with the anamorph anf teleomorph of Ascocoryne sarcoides.
Do you think the same thing ?

Roland

That part above th "5 mm" is obviously the anamorph from which you gained the phialides. But it is not clear if it is confluent with the ascomata or not. Wasn't this your question? To be sure about the species needs living spores and their size. I assume it is sarcoides. Apparentöly the spores are quite small and contain two large dops.

Zotto

Sorry Zotto, I forgot to place the details of the species.
Here they are.

Thank you ! Roland

Détails :

Date de récolte: 2008 / 10 / 27
Habitat: forêt de feuillus
Hôte: érable à sucre
Sporée non disponible

Spores cylindro-ellipsoïdes, à paroi épaisse, lisses, avec un septa, 11-14 x 4-5 µm, 12,1 x 4,8 µm en moyenne(10 spores), Q = 2,52
Asques à 8 spores uni à bisériées, avec appareil apical amyloïde, 100-130 x 8-10 µm
Paraphyses nombreuses, cylindriques, parfois un peu élargies à l’apex, souvent ramifiées à la base, septées, 100-120 x 1,5-2 µm, dépassant les asques de 10-15 µm
Excipulum ectal en textura globulosa, formé de cellules globuleuses
Excipulum ental (= medulla) abondamment gélatinisé, formé d’hyphes étroites

Conidiophores et phialioconidies présents sur des structures à la base ou près des ascomes

Spore size is at the lower limit but still o.k. Guttules are very important, however!

Here you see a vital ascus which distinctly protrudes beyond the paraphyses (contrary to the dead state which you describe), and the spores with two large guttules.
