LICHALP

Miriquidica nigroleprosa (Vain.) Hertel & Rambold var. nigroleprosa

Syn.: Lecanora nigroleprosa Vain., Lecidea nigroleprosa (Vain.) H. Magn.

Lichenised.

Substrate: siliceous 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: on hard siliceous rocks (e.g. granite) in exposed situations such as on windy ridges, starting the life-cycle on yellow Rhizocarpon-species; most often sterile, and therefore largely overlooked in the Alps.
