Schaereria fuscocinerea (Nyl.) Clauzade & Cl. Roux var. sorediata (Houmeau & Cl. Roux) Coppins

Syn.: Schaereria tenebrosa (Flot.) Hertel & Poelt var. sorediata Houmeau & Cl. Roux

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 rare sorediate morph, perhaps overlooked being mostly sterile; some of the few records from the Alps need confirmation.
