Squamarina stella-petraea Poelt

Lichenised.

Substrate: calciferous rocks, calciferous soil

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a mainly Mediterranean species with outposts in dry-warm areas of the submediterranean belt, found on calcareous rocks or on thin soil layers in dry grasslands; apparently restricted to the Western Alps (France, Italy), at low elevations.
