A taxonomic account is given on three tineid species of Morophaga in Korea. Two of them, M. formosana ROBINSON and M. fasciculata ROBINSON, are recorded for the first time from Korea. The remaining one is M. bucephala (SNELLEN). M. formosana is recorded as a new pest of Ganoderma lucidum (FR.) KARST, a well-known economic mushroom in Korea. M. kobella ROBINSON is newly synonymized with M. formosana ROBINSON.
