LICHALP

Pertusaria flavicans Lamy

Syn.: Pertusaria flavicans Lamy var. schistosa Erichsen

Lichenised.

Substrate: siliceous rocks, calciferous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) 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: on lime-free but mineral-rich siliceous rocks, mostly on sheltered, steeply inclined surfaces; chemically variable and in need of further study; widespread throughout the Alps.
