Hi everyone, I found this weird asco growing on wo

In the last two days, we again found an black discomycete on decorticated initial-phase-wood of thick lying logs of Abies alba we (I) cannot determine. Already in the last year we had found this species and I send here fotos of both years. When trying to find a name, I came across with Claussenomyces and with Sarea difformis, but both do not really fit (?).
The fully black, sessile apothecia about 1 mm contain short-stalked, unripe thick-walled asci smaller than 30/12 µm and inside are many very small, roundish-elongate spores that are hard to characterise. I did not find spores outside the ascus. The hymenium is covered by a black epithecium like in a lichen. Any reaction with IKI is not observable to me. The excipulum consists of brown isodiametrical thick-walled cells.
I have not good idea - can anybody provide help?
Regards from Lothar

Tromeropsis microtheca. Auch so eine Art, worüber ein Artikel von mir seit über 10 Jahren halbfertig ist.
Gerne notiere ich mir die Funddaten, auch welches Bild von welchem Fund stammt.

Hallo Zotto,
klasse - vielen Dank!
Was die Funddaten betrifft, wird sich Regina (Siemianowski - sie hat kürzlich hier mit Lophiotrema boreale "hospitiert") bei Dir melden.
Liebe Grüße nach Tübingen von Lothar

Hallo Lothar und Zotto,
diese Art hatten wir häufiger im Project!!
Alle meine Claussenomyces xylophila cf. - Funde der letzten Woche sind diese Art!
Ich hielt die Sporen für Konidien von zerfallenen Claussenomyces-Primärsporen ....
beste Grüße,
Andreas
