The main characters of Schaereria are: lecideine apothecia with a well-developed, proper exciple and a non-gelatinised hymenium with asci and paraphyses separating easily; the characteristic asci are of the Schaereria-type. The genus, with c. 16 species, belongs to the monotypic family Schaereriaceae in the order Sarrameanales. The key includes the 2 species known to occur in Italy, plus other 2 species known from neighbouring countries in the Alps, which should be looked for in Italy.
