Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a species with a blackish-brown, furfuraceous, areolate thallus and initially immersed but later protruding apothecia with a distinct thalline margins; on frequently moistened siliceous rocks, e.g. along streams; more common in NW Europe, with a record from the Western Alps (France).
