Syn.: Hypogymnia atrofusca (Schaer.) Räsänen, Hypogymnia intestiniformis (Vill.) Räsänen var. atrofusca (Schaer.) Poelt, Parmelia atrofusca (Schaer.) Cromb., Parmelia ceratophylla Schaer. var. atrofusca Schaer., Parmelia intestiniformis (Vill.) Ach. var. atrofusca (Schaer.) Hasselrot

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) 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: on wind-exposed siliceous rocks wetted by rain near or above treeline, less bound to a long snow cover than B. intestiniformis; widespread throughout the siliceous Alps.
