Asques à crochet (?), spores bisériées. Pas de réaction notable au Lugol, 50µ
Spores sans guttules, 7-10 X 3µ
Texture prismatique
Merci de votre aide

Re : Sur feuille de Populus tremula
Cher Luis
hmm, I am not prepared to say what this could be. I assume the apos look fringed with hairs and are sessile. Or is there a stalk?
The living paraphyses would be helpful, although I assume they contain cylindrical VBs as I can discern in the hairs.
Psilocistella could be a wastebasket genus, but I don't remember a species.

Re : Sur feuille de Populus tremula
This is good! Now I have an idea: Calycina subcitrina, to be found in "Calycina white, sp. aseptate".
