  The Japanese species of the Lecanora subfusca group are revised. As defined by Brodo (1984), species in this group have a crustose thallus, K(+) yellow reaction (containing atranorin), small to large calcium oxalate crystals and trebouxioid phycobionts in the apothecial margin, reddish brown to blackish disks, and colorless simple spores. In Japan, 21 species are recognized, of which four (L. andoi, L. nipponica, L. mikuraenisis and L. gongensiana) are described as new to science, three (L. megalocheila, L. perflexuosa and L. sulcata) previously treated in varietal ranks of other species are recognized at species rank, and five are reduced to synonymy. The Lecanora subfusca group is divided into two subgroups, the L. chlarotera subgroup and the L. allophana subgroup, based on large crystals or dispersed small crystals in the thalline margin.
