Greyish aquatic asco

Andreas Jacob, 08-05-2025 20:50

Good evening,

due to contstant drought I started to search for aquatic ascomycetes. Last month I found one on a submerged branch. I would assume that it`s probably growing on ash because there was a dead ash tree pretty close to the place of discovery. Poplar and fir were also present.

Spores: 10,6-122-13,8 x 2,4-3,0-3,5 (a few spores seem to have a septum)

IKI: weakly positive

Paraphyses: septated

Croizers:

Does anyone have suggestions? Many thanks for your help :)

Cheers, Andreas
