Lichenised.

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

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) 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: an ecologically wide-ranging, probably holarctic species, also present in urban environments; sometimes parasitic on other lichens (especially when on siliceous rocks); widespread throughout the Alps.
