LICHALP

Caloplaca grimmiae (Nyl.) H. Olivier

Syn.: Caloplaca congrediens auct. non (Nyl.) Zahlbr., Caloplaca consociata J. Steiner, Lecanora grimmiae Nyl.

Lichenised.

Substrate: ,

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: a holarctic, temperate to boreal-montane lichen, whose ecology and distribution are narrower than those of its host (Candelariella vitellina s.lat.); it occurs throughout the Alps, and even in the Mediterranean belt, sometimes on walls, but, contrary to the host, it is absent from urban areas; widespread throughout the Alps.
