According to phylogenetic analyses of nearly complete small-subunit ribosomal DNA sequences, the genus Nocardia should not comprise the two species Nocardia petroleophila and Nocardia amarae. N. amarae should be 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 comprise the genera Corynebacterium, Tsukamurella, Mycobacterium, Gordona, Rhodococcus and Nocardia that form a well identified and monophyletic unit. They are all characterized by a cell wall chemotype IV with mycolic acids.
根据对几乎完整的小亚基核糖体DNA序列的系统发育分析，诺卡氏菌属不应包含嗜油诺卡氏菌和苦味诺卡氏菌这两个物种。苦味菌应重新归类到戈登氏菌属，命名为苦味戈登氏菌。所有其他诺卡氏菌物种形成一个单系类群，与红球菌属的物种密切相关。建议恢复使用“CMN”这个名称，以包含棒状杆菌属、冢村菌属、分枝杆菌属、戈登氏菌属、红球菌属和诺卡氏菌属，它们构成一个明确的单系类群。它们都具有以分枝菌酸为特征的细胞壁化学型IV。
