Lichenised.

Substrate: calciferous rocks

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 sun-exposed calciferous rocks, e.g. on the top of large, isolated boulders; certainly more widespread in the Alps.
