LICHALP

Caloplaca limonia Nimis & Poelt

Syn.: Flavoplaca limonia (Nimis & Poelt) Arup, Frödén & Søchting

Lichenised.

Substrate: siliceous rocks, 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: a species of the C. citrina-group with an areolate, pale yellow thallus, the areoles and the apothecial margins developing blastidia on the entire surface; on calcareous rocks or on base-rich, hard siliceous cliffs in dry and sun-exposed to shaded and damp situations, but also on twigs of maritime shrubs or on soil, below the montane belt. The species, described from the calcareous cliffs along the coast of the Island of Marettimo, is also known from inland localities, and is certainly more widespread; earlier records might be under C. citrina s.lat.
