Lichenised.
Substrate: calciferous 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 holarctic species found in the mountains of Southern Europe; on limestone and dolomite, more rarely on base-rich siliceous rocks, most often at the top of isolated boulders in open, nitrogen-rich situations, mostly above or near treeline; widespread throughout the Alps.
