Substrate: bark, lignum

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: most common in climatically continental, but humid areas, on bark (branches and boles) of isolated trees and on lignum (e.g. wooden fences and poles); widespread throughout the Alps.
