Order Actinomycetales
Warning: In the List of Prokaryotic names with Standing in Nomenclature, an arrow (→) only indicates the sequence of valid publication of names and does not mean that the last name in the sequence must be used (see: Introduction).
Classification (Warning: see also the file "Classification of prokaryotes: Introduction").
For a detailed description of this taxon see Bergey’s Manual of Systematics of Archaea and Bacteria (BMSAB).

Note: According to Rules 15, 22 and 27(3) the name of the class Actinobacteria is illegitimate because it was proposed without the designation of a nomenclatural type. Oren (2017) proposes to designate the order Actinomycetales Buchanan 1917, 162 (Approved Lists 1980) as its nomenclatural type, based on Rule 22 of the International Code of Nomenclature of Prokaryotes.
