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 species with a verrucose-granulose, white thallus, immaginate, subglobose, black apothecia with a greenish pruina, a reddish epithecium, a yellowish hypothecium, and simple, ellipsoid, hyaline ascospores measuring 10-12 × 4-5 µm; the type, which well deserves further study, was collected on mica-schists in the Alps near Sondrio (Italy).
