Syn.: Lecidea interjecta Bagl. & Carestia non Nyl. nec (Müll. Arg.) Stizenb.
Lichenised. Poorly known taxon.
Substrate: siliceous rocks
Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)
