Syn.: Caloplaca cirrochroa (Ach.) Th. Fr. var. obliterans (Nyl.) Servít, Gasparrinia obliterans (Nyl.) Dalla Torre & Sarnth., Lecanora obliterans (Nyl.) Lamy, Leproplaca obliterans (Nyl.)

Lichenised.

Substrate: siliceous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a cool-temperate to boreal-montane, circumpolar species found in underhangs of basic siliceous rocks, especially calcareous schists, mostly in upland areas.
