Xylopsora friesii (Ach.) Bendiksby & Timdal

Xylopsora friesii is very similar to X. caradocensis from which it is distinguished by more or less round and glossy squamules and smaller simple ascospores. It contains friesiic acid.

The species grows on stump wood and coniferous bark. It prefers relic stands, such as rocky slopes, screes, relic pine forests or pine peatlands. It is a boreal-montane species. In central Europe, it is rare, but might also be overlooked. Xylopsora friesii is also quite rare in the Czech Republic, mainly distributed in forest peatlands and screes of southern Bohemia and certain river canyons.
