LICHALP

Thelidium aethioboloides Zschacke

Lichenised.

Substrate:

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: an amphibious, but usually not permanently submerged species of calciferous rocks in shaded situations, with optimum in the upper montane belt; perhaps more widespread in the Alps.
