This fits the description except for the missing thallus. The substrate is a dead tree, unidentified.

Dead Pyrenula?

These were on bark of a dead tree. And bark looked like it was disintegrating. At first I thought it was some sort of insect damage, and consulted with my insect friends, who insisted it was fungal. Only after I observed something similar (observation 92548), I thought this might be Pyrenula, or what’s left of it – lacking thallus and probably dead?
