This is my Found from 2006/ may /02 on Arctium spec. First i thinked this is Mollisia, then Pirottaea brevipila or Belonopsis asteroma. But Belonopsis asteroma growns on Carex and spores by Pirottaea brevipila does NOT hane on end round (Photos by Garcia on Zotto's DVD).

I am sure, everyone here does have experience with Pyrenopeziza arctii and can help me with maximal sure.

Les spores et le reste correspondent assez bien. Cf.Ellis & Ellis 1985, Microfungi on Land Plants et Dennis, British Ascomycetes.

En plus, les poils noirs sont assez différents et très caracteristiques chez les Pirottaea.

Hi Piotr,

Best regards,

Hi Bernard,

Thanx. On yours drawnings i can not see so long brown hairs and black ?cystals ?gel on margo. So you agree with me, that there is P.arctii?

Best,
Pimpek

ps.
This is drawning from living species?
