Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)
Note: a Mediterranean to mild-temperate lichen also known from North America, found on the base of old trees, more rarely on schists, with a single record from the Western Alps (France).
