Hello.An anamorph located on the surface of a thin
I would be grateful for any advice on this one.
Substrate: Strongly rotted coniferous wood
Macro: Apothecia 0.4 to 0.8 mm, very densely crowded, from distance appearing as a nearly black covering. Flat discs without margin and without stipe (rather semiimmersed in Subtsrate). Color dark greenish black to dark greenish-brown.
Micro: Asci about 60-70 µm long, J+ blue. Spores 5-7 x 2-3.5 µm, aseptate, mostly asymmetric, slightly pointed at one side. Paraphyses abundant, about 1 µm in diameter, agglutinated, green in mass. Excipulum consists of gelatinized, thickwalled hyphae, green in mass, turning purplish in IKI.
Thanks for any help
Stefan
with Zotto's key I arrive at D. suecica.
Best regards
Martin
Thanks a lot for the suggestion. I had a look at D. suecica and it generally seems to fit quite well microscopically. However, the dark, nearly black color seems to be a bit strange, but may be variable. I will try to find some more descriptions of D. suecica.
Best regards
Stefan
Yes, this is indeed very helpful. The black, crowded apothecia fit perfectly.
Thanks a lot
Stefan
