Caloplaca inconnexa (Nyl.) Zahlbr.

Syn.: Blastenia arenaria (Pers.) A. Massal. var. parasitica Jatta, Caloplaca percrocata (Arnold) J. Steiner var. parasitica Jatta, Caloplaca tenuatula (Nyl.) Zahlbr. subsp. inconnexa (Nyl.) Clauzade & Cl. Roux, Lecanora inconnexa Nyl.
Lichenised.
Substrate:
Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a mild-temperate species found on the top of isolated calcareous boulders and rock outcrops, on calcareous rocks wetted by rain in sunny situations, especially common on Acarospora cervina and Aspicilia calcarea. The species, as currently understood, certainly belongs to Athallia (see Nimis 2016), but the type material is likely to belong in Variospora, so that the nomenclature of this lichen might change in the near future. The relationships with C. necator still remain to be clarified.
