Lichenised.

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

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) 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, ecologically wide-ranging species found both in open woodlands and in grasslands (but only in humid areas), on mosses, mineral or organic soil, lignum (on stumps) and bark (on basal parts of old trees); one of the most common species of the genus in the Alps, with a wide altitudinal range.
