Lichenised.
Substrate: bark, lignum
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: this is one of the commonest epiphytic lichens of the Alps below the subalpine belt, with an extraordinarily wide ecological and altitudinal range. The value of L. achristotera (here treated as a synonym) is questioned by some authors, because in Lecidella the presence of a hymenial inspersion might not have the same importance as in other genera. Some records could refer to L. euphorea.
