hairy discomycete on living Acer
Khomenko Igor, 17-04-2021 15:01
Khomenko IgorHi,
I'm having trouble identifying this hairy discomycete. I observed it the first time in Dec 2019 on the bark of living Acer and yesterday I found it again on multiple tries, just on bare bark. I thought it may be some long-spored Lachnum sp., but now, because of the shape of paraphyses, I don't think so.

Pictures from 2021-
Pictures from 2019-

Asci 8-spored, croziers(+), IKI+b, 118-130x10-13um.
Ascospores very long cylindrical 55-64(90)x2.8-3.7um (observed only in asci);
Hairs hyaline, cylindrical, smooth.
Paraphyses are cylindrical, sometimes forked.

Re : hairy discomycete on living Acer
Hallo Igor,

I don't know the species but I would put it In Arachnopeziza based on hymenial characters and hairs, perhaps some inconspicious basal subiculum is present?
