unknown pyrenomycet 1

it's my first post here and I'm starting with two pyrenomycetes. I was not able to determine them with my literature.
Yesterday I found this one. Spores: 26-27 x 9-10 µm, are brown, two-celled and one half is smaller than the other. It grew on old wood of a deciduous tree.
Best wishes,
Gernot Friebes

Re:unknown pyrenomycet 1
Hi Gernot,
your photos of small conical ascomata and unequally two-celled ascospores remind me Kirschsteiniothelia aethiops. You should first check if asci are bitunicate and hamathecium composed of cellular (septate) filiform elements.
If yes, K. aethiops is characterized by obclavate asci (broader at base then at apex) and a conspicuous sheath around ascospores. Ascospores are verruculose, but this is not diagnostic.
Please come back with good photos af asci and spores!

Re:unknown pyrenomycet 1
It should be added that the species was earlier named Astrosphaeriella applanata, e.g. in Dennis 1978

Re:unknown pyrenomycet 1
the sheath can be observed on released spores only, it is quite conspicuous in water on fresh material. Otherwise all the rest is OK.
