LICHALP

Lecanora swartzii (Ach.) Ach. subsp. nylanderi (Räsänen) Leuckert & Poelt

Syn.: Lecanora subradiosa Nyl. var. nylanderi Räsänen

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 alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a lichen containing xanthones missing in subsp. swartzii, found under overhangs of siliceous rocks at high elevations; widespread in the Alps and rather common in areas with suitable habitats.
