Syn.: Lecanora coilocarpa auct. non (Ach.) Nyl.

Lichenised.

Substrate: bark, lignum

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)
