LICHALP

Xylographa soralifera Holien & Tønsberg

Lichenised.

Substrate: lignum

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 rather rare, recently-described species occurring on lignum in upland areas; perhaps more widespread in the Alps.
