LICHALP

Miriquidica disjecta (Nyl.) Hertel & Rambold

Syn.: Lecidea disjecta Nyl.

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 alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a species with a whitish thallus containing miriquidic acid, and black, sessile apothecia with a biatorine, brownish exciple, and an unpigmented hypothecium; on siliceous boulders, ecology and overall distribution poorly known; in the study area so far only recorded from the Eastern Alps in Italy (type material, on porphyric rocks near Paneveggio).
