it looked like something not related with lichens, but just in case I took the photos. Maybe next time I will have the chance of collect some material.
I already know the distinctive spores of Arthonia since I found A. cinnabarina (MO73120).

Arthonia is very disctinctive microscopically: small balloon-shaped asci and “macrocephalic” spores (one end is bigger than the other), usually septate to multi-septate or even muriform.
