LICHALP

Thamnolia vermicularis (Sw.) Schaer. var. subuliformis (Ehrh.) Schaer.

Syn.: Lichen subuliformis Ehrh., Thamnolia subuliformis (Ehrh.) W.L. Culb., Thamnolia subvermicularis Asahina

Lichenised.

Substrate: acidic soil (mostly on siliceous substrata), calciferous soil

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 arctic-alpine, circumpolar lichen found in open, wind-exposed alpine tundras; certainly widespread throughout the Alps, but not always distinguished from the typical variety.
