Genus Gordona is a new genus very recently proposed. The genus shows an intermediate feature of characters between genus Mycobacterium and genus Nocardia (Table 1). Four organisms were isolated recently: rum sputa of patients Nvi h pulmonary dieae. The organisms had been considered as if they were mycobacteria because of their acid-fastness only slighly weaker than the 3cid-fastnes. s of mycobacteria, but, by other characteristics, were identif. ed as Gordona (Table 1). The organisms were regarded as a species and named as Gordona auranticca, sp. nov., as they showed rough, orange-coloured colonies. The other species of Gordona, G. bronchialis, G. rubra and G. terrae, showed rough reddish or pinkish colonie s in air. The species G. aurantiaca was more acid-fast than the other species and lacked an ability to reduce nitrate to mitrite. As to the other distinguishing characters, it showed the same characters as the other species (Table 1).
