Diplotomma chlorophaeum (Hepp ex Leight.) Kr. P. Singh & S. R. Singh

Syn.: Buellia chlorophaea (Hepp ex Leight.) Lettau, Buellia porphyrica (Arnold) Mong., Diplotomma porphyricum Arnold, Lecidea chlorophaea Hepp ex Leight., Lecidea porphyrica (Arnold) Stizenb., Rhizocarpon chlorophaeum (Hepp ex Leight.) Müll. Arg.

Lichenised.

Substrate: siliceous rocks, intermediate rocks (such as calciferous schists)

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: a temperate, perhaps holarctic early coloniser of basic siliceous rocks and roofing tiles; overlooked, and certainly more widespread in the Alps.
