LICHALP

Cephalophysis leucospila (Anzi) H. Kilias & Scheid. var. caelivicina (Poelt & Hertel) H. Kilias & Scheid.

Syn.: Lecidea ultima Th. Fr. var. caelivicina Poelt & Hertel

Lichenised.

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

Altitudinal range: from the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: differing from the typical variety in the distinctly epilithic thallus, this lichen is found on exposed cliffs of limestone and schists rich in calcium; rare and restricted to very high mountains, perhaps not always distinguished in the Alps.
