Syn.: Caloplaca pyrithromoides (Nyl.) C.W. Dodge, Chrysomma pyrithromoides (Nyl.) M. Choisy & Werner
Lichenised.
Substrate: siliceous 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: on schists in open habitats, on dry surfaces with a short water flow after rain; poorly understood, but probably a good species known from Italy, France, and the Iberian Peninsula. The type specimen (PRA-V 03097), from the base of the Western Alps (Spotorno) was morphologically appraised by Vondrák (see Nimis 2016) and belongs to Rufoplaca.
