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: on exposed siliceous rocks, usually at the top of large boulders, sometimes overgrowing bryophytes; in the study area so far known only from the Western Alps (France).
