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: on south-facing, vertical surfaces of basic siliceous rocks which are, albeit seldom, wetted by water seepage after rain, often found near Peltula-stands, but somehow less bound to periodical seepage of liquid water; the host (Aspicilia spec.) is mostly sterile; also found in dry-continental valleys of the Alps.
