Syn.: Biatora lucida (Ach.) Fr., Lecidea lucida (Ach.) Ach., Lichen lucidus Ach.
Lichenised.
Substrate: siliceous rocks, lignum, plant debris
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: in underhangs of siliceous rocks protected from rain in humid areas, but also on a wide range of substrata (soil, exposed roots, bases of ancient trees), with a correspondingly wide altitudinal range.
