LICHALP

Acarospora scotica Hue

Lichenised.

Substrate: siliceous rocks

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 probably Mediterranean-Atlantic species of siliceous rocks wetted by rain, reaching the montane (rarely also the subalpine) belt in the Western Alps.
