Lichenised.

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

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)

Note: a cool-temperate to arctic-alpine, circumpolar species of calcareous rocks, including large pebbles, in rather sheltered situations, mostly in upland areas, with optimum above treeline; widespread throughout the Alps.
