Altitudinal distribution: alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)
Note: a lichen with a non-effigurate, coarsely areolate thallus and soralia developing from verrucose areoles, the soredia transforming into isidia; on periodically submerged rocks and boulders along Alpine streams; the distribution is still insufficiently known.
