You are right, it doesn’t seem lichenized.

You proposal is good, I can’t see nothing better. However, the spores are a bit too wide.

Apparently not

Brown septate spores are typically Physciaceae (consider Cyphelium maybe? I doubt it), but I wonder in this case if it’s even lichenized. The asci don’t look like typical Lecanoromycetes. British Flora suggests Melaspilea. Plausible. M. bagliettoana (known from Britain and Morocco) is “probably not obligately lichenized”.

Jason, do you know …
