LICHALP

Lecanora bicincta Ramond var. bicincta

Syn.: Lecanora rupicola (L.) Zahlbr. var. bicincta (Ramond) Clauzade & Cl. Roux, Lecanora sordida (Pers.) Th. Fr. var. bicincta (Ramond) Th. Fr.

Lichenised. Poorly known taxon.

Substrate: siliceous rocks, intermediate rocks (such as calciferous schists)

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 holarctic lichen found on vertical to underhanging surfaces of hard siliceous rocks. According to Roux et coll. (2014) this is just a morphotype of L. rupicola, transitional forms being common; widespread throughout the Alps.
