Hello everybody,
Any help on this one would be much appreciated:
Ecology: decorticated hardwood, likely Acer pseudoplatanus
Macro:
Perithecia in groups of variable size immersed in the wood. The surface area around the emerging ostioles is blackened. Ostioles are minutely umbilicate. The wood surrounding the perithecia is not conspicuously discoloured and there is no black line in the wood. Perithecial diameter 0.3-0.6 mm, necks 0.2-0.6 mm.
Micro:
Spores centrally septate, greenish brown, smooth, with a large guttule in each cell and a rather well visible germ Pore on one side, 11-14.5 x 5.0-5.6 (-6.0) µm. Asci 110-140 x 6-7 µm with an inconspicuous but visible apical apparatus that shows no iodine reactions.
Best wishes and many thanks,
Stefan

Re : Endoxyla s.l.?
Hi Stefan,
I think everything in your excellent images matches with Pseudovalsaria ferruginea.
For differences with Endoxyla you can refer to
Untereiner et al Mycologia, 105(3), 2013, pp. 564–588. DOI: 10.3852/12-326
All the best,
Jacques

Re : Endoxyla s.l.?
Many thanks, Jacques!
I should have known the species, but the nearly lacking stroma confused me too much.
The other collection looked like this...

Re : Endoxyla s.l.?
the first collection is more typical. The other stroma likely became superficial by disintegration of the surrounding strongly rotten wood. Tricky!
