Bonjour, Je cherche des indices pour cette récolte sur bois mort (Plus probablement Acer sp.) au sol Apos 0,10-0,15 mm, hyalines à blanchâtres , un peu granuleuses d'aspect, très fragiles
Asques avec crochets, , IKI négatif , en moyenne 60 x 16 µm, Spores 10-12 x 5-6 µm.
Paraphyses remarquablement larges, avec VBs (CRB +) Ectal prismatica avec VBs
Merci pour tout indice,
Amitiés. Michel

Re : Help for Genus and Species ID
Hard to tell. Seems there is an inamyloid apical dome in dead asci.
The VBs speak for a Pezizellaceae. Mo idea. Perhaps the excipulum could narrow the relationship?

Re : Help for Genus and Species ID
Thanks, Zotto,
I did search in the Pezizellaceae after observation of the prismatica type ectal , full of VBs ...
but found no match

Re : Help for Genus and Species ID
Peut-être une idée stupide, mais pourquoi pas un champignon lichénisé ? Il me semble apercevoir sur les photos macros ce qui pourrait être un thalle...

Re : Help for Genus and Species ID
Asci and spores indeed resemble some lichens, maybe Agyrium, but inamyloid hymenia in lichens I think are very rare. It would be the first case of VBs occurring in lichens.
I am not sure if the apothecia survive drought. What is the substrate and how was the situation when you found it, Michel?
Your pics show the cortical layer of the excipulum, but how is it more inside? I fear the fungus is too small to obtain a section.

Re : Help for Genus and Species ID
perhaps what I suggest is ridiculous, but this fungus reminds me to some extent of Mniaecia, e.g. M. gloeocapsae s.l. - but I know those usually grow on soil. But perhaps the algae are more important?

Re : Help for Genus and Species ID
Mniaecia so far never had VBs. it would surprize me.
