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 of uncertain affinity, with a whitish, areolate thallus developing on a conspicuous black hypothallus, plane, black, often deformed and confluent apothecia with a plane disc and a thin proper margin, a greenish-brown epithecium, a thin hymenium of coherent paraphyses, a colourless hypothecium, 8-spored asci, and elliptical, hyaline, simple ascospores which are c. 2 times as long as wide; only known from the type collection, on schists, which deserves further study.
