Lecidella asema (Nyl.) Knoph & Hertel var. elaeochromoides (Nyl.) Nimis & Tretiach

Syn.: Lecidea catalinaria Stizenb., Lecidea elaeochromoides (Nyl.) Flagey, Lecidea parasema (Ach.) Ach. var. elaeochromoides Nyl., Lecidea subincongrua Nyl. var. elaeochromoides (Nyl.) Poelt, Lecidella elaeochromoides (Nyl.) Knoph & Hertel, Lecidella subincongrua (Nyl.) Hertel & Leuckert var. elaeochromoides (Nyl.) Hertel & Leuckert

Lichenised. Poorly known taxon.

Substrate: siliceous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: the chemistry of L. asema is quite complex; this variety with a yellow thallus is common in the Mediterranean region, and so easily recognizable, that we still prefer to distinguish it from L. asema s.str., at least at varietal level; in the Alps it is most frequent in the dry-warm valleys of the Alps.
