LICHALP

Physconia perisidiosa (Erichsen) Moberg

Syn.: Physcia perisidiosa Erichsen, Physconia farrea auct. et sensu Poelt non (Ach.) Poelt

Lichenised.

Substrate: bark

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 Mediterranean to mild-temperate lichen with a fragmented holarctic distribution, found both on bark and on epiphytic mosses; most common in submediterranean areas with a warm-suboceanic climate, but rare in disturbed habitats; widespread throughout the Alps below the subalpine belt.
