Pyrenomycet on Fagus: Lophiotrema?
Regina Siemianowski, 17-09-2015 22:48
Hi to all,
today I have found a black, immersed perithecia on coarse woody debris of Fagus, initial stage of decomposition. There is an elongated crest-like ostiolum.
Spores are allantoid, 13–14 µm x 3-3,5 µm, hyaline, two-celled with a constriction at the septum.
Asci 60-90x4-5µm, with 8 spores
My first idea was Lophiotrema boreale, certainly I'm completely wrong.

Thanks in advance for any suggestions!
Regina

Yes, L. boreale, no problem.
