Substrate: bark, lignum, siliceous 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 boreal-montane species found in oroboreal-montane forests with high rainfall and frequent fog, especially on branches and twigs of Picea. This is one of the most frequent and morphologically most variable species of the genus; widespread throughout the Alps.
