LICHALP

Placynthium garovaglii (A. Massal.) Malme

Syn.: Placynthium caesium auct., Racoblenna garovaglii A. Massal.

Lichenised.

Substrate: calciferous rocks

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 steeply inclined, sunny surfaces of calcareous rocks with some water seepage. The species name is often spelled garovaglioi, but the latinised name of Santo Garovaglio (who wrote most of his works in Latin) was Garovaglius, whose genitive is garovaglii.
