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 species of unclear relationships with a thick, whitish to bluish-grey thallus of ramified and unequally thick particles, and adnate, black apothecia which are at first plane and marginate, later convex and immarginate, based on a type from Northern Norway where it appears to be more common; on mosses and soil in alpine environments, rarely reported from the Alps.
