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: a holarctic lichen found on the base-rich bark of isolated trees, e.g. on Populus, Juglans, Fraxinus, Sambucus, mostly in Xanthorion-communities; some earlier records could refer to L. cyrtellina and L. sambucina; widespread throughout the Alps.
