Eleven species are recognized of which C. bogilana and C. subflavorubescens are described here as new to science while nine species (C. cinnabarina, C. decipiens, C. ferruginea, C. inconspecta, C. pellodella, C. scopularis, C. stantonii, C. squamosa and C. subsoluta) are reported for the first time for South Korea. Both new species are peculiar due to their secondary chemistry; anthraquinones along with atranorin, gyrophoric acid and lecanoric acid in C. bogilana, and gyrophoric acid together with anthraquinones in C. subflavorubescens.
