LICHALP

Arthonia calcicola Nyl.

Syn.: Allarthonia calcicola (Nyl.) Redinger

Lichenised.

Substrate: calciferous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)

Note: an early coloniser of calcareous walls and mortar; overlooked and probably more common, especially in the eu-Mediterranean belt, and also present in the warm-dry valleys of the Alps.
