Schaereria cinereorufa is a montane saxicolous lichen with an areolate-squamulose thallus and black lecideoid apothecia. Microscopically, it is well-identifiable thanks to globose ascospores and blue-green pigment in the upper part of the hymenium. It prefers open, but wind-protected, rock outcrops. The species usually grows in crevices of steeply inclined or vertical surfaces of siliceous boulders and rocks rich in minerals, such as phyllites. In the Czech Republic, it is historically only known from the highest elevations, mainly in the Krkonoše Mts (see the catalogue by Vězda & Liška 1999). The most recent records are from the Jeseníky Mts, Krušné hory Mts and the Šumava Mts, where it was also recorded by Hilitzer (1929, as Lecidea cinereorufa).
