This is one of those species with irregularly-stacked thallus units with black lines between the bits, and perithecia immersed irregularly among them. There’s a black hypothallus/prothallus. The involucrellum is undeveloped. Hymenium is I+ red, K/I+ blue. Spores are ~12-18×5-8µm but mostly on the shorter side.

the lichen of interest here is not the black background (Acarospora?), but the small protruding lumps scattered here and there, some bearing perithecia (?) on tips of lumpy thallus. On dolomite latticework.
