Hi everybody

I found this Asco on prev.years stem of Potentilla-erecta.

Ectal excipulum build of brown t.globulosa, at base sometimes strongly cylindrical. Subiculum negative but some syphae are presents, 1,5um thick, light brown.
Hairs hyaline/light brown/brown, septate. Marginal hyalime, thin long cells, 1-2 septate.
Asci and spores are visible on my quick-drawning. I can not found paraphyses, cause my collection is infected by konidial parasite.

I think it can be Mollisia potentillae-erectae Svrèek (1988), but on Potentilla spec. can be found also Pyrenopeziza coloradensis and Pyrenopeziza potentillae - i have not describtion of this species.
