LICHALP

Lecidea haerjedalica H. Magn.

Lichenised.

Substrate: siliceous rocks, metal-rich 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 alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: an arctic-alpine, silicicolous species of wind-exposed, snow-free sites, most frequent on crystalline schists near or above treeline; from the Alps there are several scattered records.
