LICHALP

Parabagliettoa disjuncta (Arnold) Krzewicka

Syn.: Verrucaria disjuncta Arnold, Verrucaria tristis (A. Massal.) Kremp. f. depauperata (A. Massal.) Arnold

Lichenised.

Substrate: calciferous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a formerly very poorly understood species growing on inclined to vertical surfaces of calcareous rocks; probably more widespread in the Alps.
