White hairy on Populus tremula leaf

size of these is up to 1 mm.
The spores are about 10-15x2-3.
Asci are about 46-60x6-7 and faintly IKI blue.
The paraphyses are up to 5 mm wide, lanceolate and septate and exceed asci a bit or not at all.
The hairs are septate, up to 5 mm at the base, up to 100 long and carry some matter.
I did not check KOH reaction, because I have not met such a stipate species, where it would have been necessary.
Once again I miss the genus to look for species: Marja

Re : White hairy on Populus tremula leaf
Hi Marja
did you consider Lachnum virgineum? There was a species erected fr leaves but I never believed that it is separate (L. charretii).
No, spores are too large. Perhaps DASYSYPHELLA CLAVICULATA.

Re : White hairy on Populus tremula leaf
Dear Zotto,
thank you!
I was lucky to find revision of the genus Dasyscyphella by Raitviir.
I know he studied dried specimen, so the bigger size of spores and asci of my finding can be accepted.
Dasyscyphella claviculata is a good option for determination.

Re : White hairy on Populus tremula leaf
If you find hexagonal crystals among the hairs then it wouldbe for sure.
