Stereocaulon botryosum Ach.

Syn.: Stereocaulon alpinum Laurer var. botryosum (Ach.) Laurer, Stereocaulon evolutum Graewe var. fastigiatum (Anzi) Th. Fr., Stereocaulon fastigiatum Anzi

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: an arctic-alpine, probably circumpolar lichen found on steeply inclined surfaces of siliceous rocks in humid-shaded situations, with optimum above treeline.
