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: a silicicolous species with a pale yellow, pulverulent, rimose to areolate thallus, and innate to sessile, marginate apothecia with black convex discs; only known from the type locality in the Western Alps (Switzerland), on granite.
