Toninia squalescens (Nyl.) Th. Fr.

Syn.: Lecidea squalescens Nyl., Thalloidima rimulosum Th. Fr.
Lichenised. Poorly known taxon.
Substrate:
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: on silicicolous mosses, mostly on Andreaea near or above treeline; on the whole, a rather poorly known species which certainly does not belong to Toninia.
Austria: Vorarlberg; Tirol; Salzburg; Switzerland: Valais; Italy: Lombardia;
