Hans-Otto BaralHere I have an old collection (7.3.1993), from  Luxembourg, Fentange, attached old branch of Salix caprea, soc. Deltopyxis, Dactylospora etc.

The spores mesured *12-13 x 5.5 µm, now in KOH 13-14 x 4.2-4.8 µm, light greybrown. Asci IKI-.

The perithecia collapse when dry and occur abundant among long black setae on decorticated wood. So I assume to search in Acanthonitschkea.

Any idea?
