Lichenised.

Substrate: calciferous soil, acidic soil (mostly on siliceous substrata)

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) 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: on humus-rich soil in alpine grasslands; probably more widespread in the Alps.
