Syn.: Baeomyces rubiformis Ach., Lecidea rubiformis (Ach.) Wahlenb.

Lichenised.

Substrate: calciferous rocks, intermediate rocks (such as calciferous schists), calciferous soil

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: an arctic-alpine species found on loess and calciferous soil, in fissures of calciferous siliceous rocks (e.g. calciferous schists); chemically heterogeneous (with and without gyrophoric acid).
