Hello.A very tiny pyrenomycete sprouting sparsely
blanc poilu
Louis DENY,
23-12-2025 11:27
sur débris de bois de feuillu (acer pseudoplatanus?):
apothécie blanche, sessile, urcéolée puis s'applatissant avec l'âge, diametre 0.3-0.5 mm
poils enflés et poilus à l'apex de longueur de 40 microns,
asques entre 90 et 100 microns, spores unisériés, réaction positive au lugol,
spores de 12 - 14 3- 4 microns, OCI 2-3, quelques gouttes moyennes
paraphyses filiformes, de la taille des asques
excipulum prismatique
Je cherche dans les Cisstella, du fait de l'aspect des poils, mais ne voit rien qui corresponde à ces dimensions de spores et d'asques
Merci de me remettre sur la bonne voie

Re : blanc poilu
Bonsoir Louis,
To me this looks like Cistella dentata, the hairs are a bit longer but can fit in the species.
Regards,
Stip

Re : blanc poilu
Many thanks for the hint, Stip
I considered this species, but excluded it because of micro size, especially asci. Now, when looking at Zotto's folder, I see there is a 'dentata like' having shorter size. It's seems there is much variation in the micro of this species.
