I hope someone can help me with this one. It reminds me on Lophiostoma, but I did not find a fit there. I also stumbled over Kirschsteiniothelia which looks similar, but I have not enough Literature.
Substrate: Wood, probably coniferous, but I'm not sure. The fruitbodies are partly overgrown by a corticioid basidiomycete (Hyphodontia aspera).
Macroscopic description:
Fruitbodies immersed, semiimmersed or nearly superficial, about 0.4-0.5 mm in diameter, black, with a slit-like opening.
Microscopic description:
Perithecial wall with very dark brown, mostly isodiametric to somewhat elongated cells, thick (partly >100 µm). Asci bitunicate, J-, 90-120x10-12 µm. Spores dark brown, two-celled, constricted in the middle and often rather pointed outwards, with several small drops in water and mostly two large drops in CR or J, 15-18 x 6-7 µm. Spores have an inconspicuous but rather large slime sheath.
Thank you for any help
Stefan
obwohl die Fruchtkörper nicht deutlich zu sehen sind und bei Byssolophis ampla die Sporen üblicherweise lange hyalin bleiben, würde ich auf diesen Pilz tippen.

Vielen Dank für den Tipp. Ich werde dann mal Literatur zur Art suchen und vergleichen.
