LICHALP

Peltigera scabrosa Th. Fr.

Syn.: Peltigera genuina Gyeln., Peltigera pulverulenta auct. non (Taylor) Nyl., Peltigera sancti-stephani Gyeln.

Lichenised.

Substrate: living mosses, acidic soil (mostly on siliceous substrata)

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 circumpolar, mainly arctic-alpine lichen found on mossy soil and rocks near and above treeline; quite rare in the Alps.
