LICHALP

Lecanora freyi Poelt

Lichenised.

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

Note: a rosulate species with minute lobes recalling small thalli of Lecanora valesiaca, and apothecia with brownish-greenish to dark green discs; on steep rock faces of calcareous schists at high elevations; widespread in the Alps, but altogether rare.
