Lichenised. Poorly known taxon.
Substrate: bark, lignum, living mosses, rocks,
Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a temperate to boreal-montane, morphologically and chemically variable species found on basal parts of old, acid-barked trees in montane forests, and on a wide range of other substrata; in its present circumscription this is one of the most common species of the genus in the Alps; however, this taxon represents a complex assemblage of species, yet to be properly disentangled.
