Lecidea obluridata Nyl.
Lichenised.
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)
Note: a silicicolous species resembling L. fuscoatra, but thallus containing confluentic acid, apothecia adnate, flat, with thin margins, hypothecium brown, and ascospores oblong, c. 10 µm long; based on a type from low elevation in the Pyrenees; the distribution in the Alps is poorly known.
