LICHALP

Thelopsis flaveola Arnold

Lichenised.

Substrate: bark

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 mainly temperate species found on bark of ancient deciduous trees, but also, in the subalpine belt, on bases of old Rhododendron shrubs; to be looked for further in the Alps.
