Hello everybody

It would be great if someone had an idea about this pyrenomycete.

It is on bark of a small branch of deciduous wood. The Perithecia are only 0.2-0.3 mm in diameter and about 0.2 mm high, black and rounded to conical. There is no pore visible.
The spores are rather special, thats why I think it could be identified:
Spores 60-85 x 3.5-4.5 micros, broadly rounded at one end and tapering to the other, rather pointed end, giving them a slender club-shape (see Photos), hyaline with about 6-8 transversal septa and filled with small oildrops, which makes the Septation difficult to see. The pointed half is sometimes strongly bent. Asci 110-125 x 10-12 micros. Paraphyses(?) densely packed, septate.

Thanks for any Ideas
Stefan
