The asexual state (rather non-descript grey-green 'fingers') are present (especially in the final photo).

This could be an Annulohypoxylon but the genus Daldinia is another possibility. You find the most striking feature of Daldinia by looking at a cross section. Internally it is concentrically banded in several alternating layers of black and white.

Your first photo may show (but I'm not certain) a few examples of the asexual state of this fungus. I'm referring to the short, pale, greyish brown stalks that are near the dark wood/light wood boundary, about a fifth of the way up from the bottom. You see a couple of clusters, the stalks in each cluster originating from a common point. You see more examples of the asexual state here: https://canberra.naturemapr.org/sightings/3343988.

Great. Many thanks for that ID Heino and the additional information re Liliane Petrini and the dissolving asci!

While I’ll leave this in ‘Rosellinia group’, I suspect this is a Rosellinia proper. Lots of spores, but I didn’t find any asci. However, I then found out something new to me. In a paper about Rosellinia by Liliane Petrini (who has studied the genus in depth), I read this sentence: The asci dissolve very quickly and are rarely seen in mature material.
