Dear collegues,
during a research on teleomorphs of aquatic ascomycetes we came across this pyrenomycete today, on submerged log of Fagus.
The macrofoto is quite bad, sorry! But may be it is still a little bit helpful. The perithecia are single, black and nearly superficially seated, in small group but never toucing one another.
Spores multicellular, first hyaline than brown, becoming 8-celled, with an hyaline appendix (not always visible), appr. 90 x 18 µm
Asci bitunicate (?)

Hallo Lothar,
