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 the L. swartzii-group but recalling L. bicincta in the areolate thallus and the blackish inner parathecial rim; on vertical to overhanging faces of siliceous cliffs; in the study area so far only reported from the Eastern Alps.
