LICHALP

Placopyrenium canellum (Nyl.) Gueidan & Cl. Roux

Syn.: Verrucaria aspiciliae Zehetl. non (J. Lahm) Stizenb. nec Vain., Verrucaria aspiciliicola R. Sant., Verrucaria canella 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 very common saxicolous species which starts the life-cycle on species of the Aspicilia calcarea-complex; certainly more widespread in the Alps, but formerly misunderstood.
