Caloplaca necator Poelt & Clauzade

Syn.: Caloplaca inconnexa (Nyl.) Zahlbr. var. nesodes Poelt & Nimis, Athallia nesodes (Poelt & Nimis) Halıcı & Vondrák comb. inval.
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: a mainly Mediterranean species found on siliceous rocks, starting the life-cycle as a parasite of Aspicilia-species, especially A. viridescens. According to Roux et coll. (2014) the smaller size of spores distinguishing C. necator from C. inconnexa var. nesodes is due to the fact that the holotype material of the former is poorly developed: other specimens (isotype) collected at the type locality show the same spore size range as the latter taxon.
