The relationship is based on a similar morphology, cell wall composition, as well as 16S ribosomal ribonucleic acid (rRNA) gene sequences. All the three species differ from other corynebacteria by the presence of large amounts of fatty acids. Colonies of all the three species form gray–brown...

They are nonmotile and catalase-positive and contain mycolic acid in their cell walls. Clinically relevant species include C. diphtheriae, C. jeikeium, C. pseudotuberculosis, C. xerosis, Corynebacterium amycolatum, Corynebacterium pseudodiphtheriticum, Corynebacterium minutissimum, Corynebacterium ...
