LICHALP

Evernia divaricata (L.) Ach.

Syn.: Letharia divaricata (L.) Hue, Lichen divaricatus L.; incl. Evernia perfragilis Llano

Lichenised.

Substrate: bark, lignum, plant debris,

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a cool-temperate to southern boreal-montane, circumpolar lichen found on twigs of coniferous and deciduous trees in semi-natural, humid, montane to subalpine forests; albeit very rarely, it also occurs on soil on windy ridges with frequent fog; widespread throughout the Alps.
