I have not collected a specimen, but I can if revisit and collect, nonetheless the cross section of the stroma reveals some data that might be helpful
So to conclude I assume this is a Biscogniauxia sp. and wonder if from the photos we can determine the species - maybe Biscogniauxia mediterranea ?
Tnx

Re : Biscogniauxia sp.
Hi Mario
More than likely, but it would be better to know what the spores look like or at least to be able to see the typical pyramidal neck of the perithecia.

Re : Biscogniauxia sp.
Hello, so I have worked a bit more on this carbonaceous fungus.
The host was Quercus ilex
The ostiole is surrounded by a pyramidal projection, like a volcano
The Peritheca a single layer of cylindrical structures, 0.8mm long, 0.2um wide, pentagonal cross-section, sitting on a thin black layer about 50-80um thick
The spores elliptical about 15-19 um long with a longitudinal pale central band.
(14.7) 15.3 - 18.3 (19.3) × (6.4) 7.1 - 8.1 (8.4) µm
IK+, the rim stains like a broad U shape hence haveing a bowl-shaped
I think we can conclude and confirm B. mediterranea
