Lichenised.

Substrate: calciferous rocks

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: an arctic-alpine, circumpolar species with southern outposts in steppic-continental regions, found in fissures of calciferous rocks; when young it often overgrows cyanobacterial colonies and cyanobacterial lichens; widespread throughout the Alps.
