Lichenised.
Substrate: siliceous rocks
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 temperate to boreal-montane, perhaps circumpolar lichen found on moist siliceous rocks (inundation zones along streams, seepage tracks), often near mountain rivulets.
