The Mycobacteriales are an order of bacteria. The current description is genome-based, per Gupta 2019 emendation. Most members produce mycolic acids.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN).
Mycolata has been used as a non-taxonomic term for mycolic acid-containing Actinobacteria. Mycobacteriales includes all such species, but it also includes some without mycolic acid, making these two terms imperfect, paraphyletic, aliases.
