Lichenised.

Substrate: intermediate rocks (such as calciferous schists)

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 more or less arctic-alpine species found on base- or lime-rich siliceous substrata, periodically submerged in cold creeks, or in seepage tracks; so far only recorded from a few scattered localities in the Alps.
