small black asco on moist Hepaticae-lawn from Norway
Lothar Krieglsteiner, 05-08-2022 13:22
Lothar Krieglsteinernear Snasa, on mixed lawn with Nowellia curvifolia on old pine trunk, 10.7.22. The spores I measured about 24-30/7-9,5 µm. Quick check in Racovitza or Doebbeler did not lead to a good result. Does somebody have a hint?
Regards, Lothar

no, Zotto - there is nothing blue. Maybe this impresion is from artificial light. All picture are from one fungus, a pyrenomycete.
Yours, Lothar

Re : small black asco on moist Hepaticae-lawn from Norway
Interesting one.

Epigloea sp. parasitic on the algae? Some can have large ascospores like that but the structure of the fruitbody seems wrong (textura angularis vs t. intricata). Have you checked the iodine reaction for the orange hymenial gel of Epibryacae? The spores are somewhat in the range of Bryomyces gymnomitrii. Wrong host but that genus has members that grow on multiple hosts. Another genus to consider is Bryorella.

All the best,

Hello Georges,
thank you very much for your very valuable contribution. I will go back to the specimen later (likely in winter) and try to clarify your questions. Funny: Bryomyces gymnomitrii was one of the few species I came across with, too. But I rejected because there is no Gymnomitrium.
Thanks again and best regards, Lothar
