LICHALP

Aspicilia caesiocinerea (Nyl. ex Malbr.) Arnold

Syn.: Aspicilia gibbosa auct. non (Ach.) Körb, Aspicilia rolleana Hue, Circinaria caesiocinerea (Nyl. ex Malbr.) A. Nordin, Savić & Tibell, Lecanora caesiocinerea Nyl. ex Malbr., Lecanora rolleana (Hue) Zahlbr.

Lichenised.

Substrate: siliceous 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 siliceous rocks wetted by rain, with a wide altitudinal range. Very heterogeneous both morphologically and ecologically, and in need of revision; widespread throughout the Alps.
