Bonsoir forum


Sur feuille d'arbre (sans doute populus tremula) ce petit (diamètre 1 mm) disque blanc à poils courts
Poils lisses, séptés, extrémités arrondies, moins de 50µ
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

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".
