Abstract
According to phylogenetic analyses of nearly complete small-subunit ri bosomal DNA sequences, the genus Nocardia should not comprise the two species Nocardia petroleophila and Nocardia amarae. N. amarae should b e reassigned to the genus Gordona as Gordona amarae. All of the other Nocardia species form a monophyletic unit, closely related to species of the genus Rhodococcus. It is proposed to revive the name 'CMN' to c omprise the genera Corynebacterium, Tsukamurella, Mycobacterium, Gordo na, Rhodococcus and Nocardia that form a well identified and monophyle tic unit. They are all characterized by a cell wall chemotype IV with mycolic acids.
