It was difficult to cut off even a small piece. I don’t carry an axe!

Margin is somewhat fibrous.

And has it got pores? On the last pics it suggests to have pores. Or something in the vein. I now go for Corticiaceae or Polyporales or even Agaricales. Scope work would be urgently needed for this interesting one!

is a broad leaf forest. Consistency was very firm. If I get to the site again I’ll try to get better pictures and a voucher. I did not see any Exidia.

Hypocrea sulphurea is always associated with Exidia glandulosa, it seems to be in some partnership/parasitism with that fungus. But sometimes Exidia cannot be seen on the substrate anymore because of too old an age or when it is extremely dried up. Or Hypocrea can still be present when Exidia is gone. But usually you’ll see both species on the log.
Furthermore, Hypocrea has ostioles that should be visible under strong magnifying glass or high resolution pics. What about the consistency of that fund? Crumbly, hard, soft, cottony? Anything else noteworthy? Host? I have never found it on conifers but since Exidia can be found on conifers as well I do not want to rule that out. Do you have any better photos? Or can you go back to the spot for more photos or collecting a voucher specimen?
For now this could be anything, either asco or Corticiaceae. Possibility of Hypocrea not ruled out though.
