Lichenised.

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

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) 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 found on mosses and soil rich in humus in sheltered situations, older thalli are lichenised, younger ones are lichenicolous on Baeomyces; widespread throughout the Alps.
