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 thallus consisting of scattered, brown, hemispherical areoles, often with immersed apothecia, hymenium practically without paraphyses, and polysporous asci containing subspherical ascospores up to 5 µm in diam.; on moist siliceous rocks; rare in Europe from the boreal to temperate-montane zones, with a single record from the Western Alps (France).
