LICHALP

Stereocaulon rivulorum H. Magn.

Lichenised.

Substrate: acidic soil (mostly on siliceous substrata)

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 to boreal-montane lichen found on gravel and sand in snow-beds or on banks of streams near glaciers, sometimes on weakly calciferous schists.
