Caloplaca subochracea auct. non (Wedd.) Clauzade & Cl. Roux var. subochracea
Lichenised.
Substrate: calciferous rocks
Altitudinal distribution: mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex)
Note: a group of closely related taxa with a rimose to areolate thallus of various colours and rusty-brown apothecia; on limestone boulders and outcrops at sites not far from the Mediterranean sea, usually in rather shaded situations; widespread but not common, in the study area only known from low elevations at the base of the Western Alps. There are open issues with the epithet of this lichen, since the type material by Weddell corresponds to a species which is not the same as that called Caloplaca subochracea by most recent authors (see Roux et coll. 2014). Furthermore, according to Nimis (2016) the type of Callopisma marmoratum Bagl. (MOD-TSB) clearly belongs to this lichen and not to that which is usually called “Caloplaca marmorata” by most authors.
