Lichenised.

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

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 to cool-temperate, circumpolar lichen mostly found on rotting wood, more rarely on soil rich in humus, bryophytes and peat, mostly in clearings of grasslands and shrublands, with optimum near treeline; widespread throughout the Alps.
