Lichenised.

Substrate: acidic soil (mostly on siliceous substrata), siliceous rocks, lignum, living mosses

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 holarctic early coloniser of acid soils with high clay content and of weathered siliceous rocks, often found in disturbed sites; mostly sterile in upland areas; widespread throughout the Alps.
