bitunicate ascomycete on wood in rivulet - Lophiostoma?
Lothar Krieglsteiner, 09-08-2020 22:18
Lothar Krieglsteiner... the spores of this find (today, in the Eifel, Germany, on decorticate decideous wood, likely Alnus, in a rivulet) remind me of Lophiostoma - but he ascomata are not laterally compressed. The asci are quite long, ca. 100-120/10-13 µm, the spores about 25-32/6-7 µm large, with conspicuous oil drops. Old and dead spores tend to become brown, living spores are hyaline.
Who can provide me with a hint?
Best regards, Lothar

Re : bitunicate ascomycete on wood in rivulet - Lophiostoma?
Hola Lothar.
Por opinar algo, aunque las esporas son un poco grandes, me parece apreciar una vaina mucosa, quizás Lophiostoma vagabundum, dejo un par de enlaces;

You may want to consider Massarina corticola and Amniculicola parva. The latter grows on submerged wood (described from Alnus) and stains the underlying wood sometimes purple. Did you note a gelatinous sheath?

Hello Josep and Eduard,
thank you both for your proposals - three ones :-)
I did not note a purple stain of the wood, nor did I note a gelatinous spore sheath, but maybe the latter I possibly overlooked. I will try to examine again.
Best regards and thanks again,
Lothar
