Catillaria melanophaea (Anzi) Lettau

Syn.: Biatorina melanophaea Anzi, Lecania melanophaea (Anzi) Zahlbr.
Lichenised. Poorly known taxon.
Substrate: siliceous rocks
Altitudinal distribution: 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 brownish, rather thick, rugulose, rimose-areolate thallus, small, adnate apothecia with a rather convex, dark brown, scabrid disc and a thin, finally disappearing margin which has the same colour as the thallus, a brownish epithecium, a pale hypothecium, coherent paraphyses, 8-spored asci and 1-septate, hyaline, straight to curved ascospores measuring 15.4-17.2 × c. 8.6 µm; the taxonomic position of this species, known only from the type collection on mica-schists, needs clarification.
