| Proposed phylum name | Nomenclatural type (class) | Phylum name currently in common use | Comments |
|---|---|---|---|
| Acidobacteriota | Acidobacteria | Acidobacteria cannot be used as the name of the class as it is on the list of nomina rejicienda (Opinion 79). Instead we propose Acidobacteriae | |
| Actinobacteriota | Actinobacteria | Actinobacteria | Note that no nomenclatural type has been designated for the class Actinobacteria |
| Alphaproteobacteriota | Alphaproteobacteria | Proteobacteria | As the name Proteobacteria is widely used for the phylum, the Judicial Commission may consider conserving this name (earlier used for a class) instead of Alphaproteobacteriota |
| Aquificota | Aquificae | Aquificae | |
| Armatimonadota | Armatimonadetes | We propose establishing the class Armatimonadia as the nomenclatural type | |
| Bacillota | Bacilli | Firmicutes | As the name Firmicutes is widely used for the phylum, the Judicial Commission may consider conserving this name instead of Bacillota |
| Bacteroidota | Bacteroidia | Bacteroidetes | |
| Caldisericota | Caldisericia | Caldiserica | |
| Chlamydiota | Chlamydiae | Chlamydiae | |
| Chlorobiota | Chlorobi | Chlorobea cannot be used as the name of the class as it is on the list of nomina rejicienda (Opinion 79). Instead we propose Chlorobia | |
| Chloroflexota | Chloroflexia | Chloroflexi | |
| Chrysiogenetota | Chrysiogenetes | Chrysiogenetes | |
| Deferribacterota | Deferribacteres | Deferribacteres | |
| Deinococcota | Deinococci | Deinococcus-Thermus | |
| Dictyoglomota | Dictyoglomia | Dictyoglomi | |
| Elusimicrobiota | Elusimicrobia | Elusimicrobia | |
| Fibrobacterota | Fibrobacteria | Fibrobacteres | |
| Fusobacteriota | Fusobacteriia | Fusobacteria | |
| Gemmatimonadota | Gemmatimonadetes | Gemmatimonadetes | |
| Ignavibacteriota | Ignavibacteria | Ignavibacteriae | |
| Lentisphaerota | Lentisphaeria | Lentisphaerae | |
| Methanobacteriota | Methanobacteria | Euryarchaeota | As the name Euryarchaeota is widely used for the phylum, the Judicial Commission may consider conserving this name instead of Methanobacteriota |
| Mollicutota | Mollicutes | Tenericutes | Note that no nomenclatural type has been designated for the class Mollicutes |
| Nitrososphaerota | Nitrososphaeria | Thaumarchaeota | As the name Thaumarchaeota is widely used for the phylum, the Judicial Commission may consider conserving this name instead of Nitrososphaerota |
| Nitrospirota | Nitrospira | We propose establishing the class Nitrospiria as the nomenclatural type | |
| Planctomycetota | Planctomycetes | Planctomycea cannot be used as the name of the class as it is on the list of nomina rejicienda (Opinion 79). Instead we propose Planctomycetes | |
| Spirochaetota | Spirochaetes | Spirochaetes cannot be used as the name of the class as it is on the list of nomina rejicienda (Opinion 79). Instead we propose Spirochaetia | |
| Synergistota | Synergistia | Synergistetes | |
| Thermodesulfobacteriota | Thermodesulfobacteria | Thermodesulfobacteria | |
| Thermomicrobiota | Thermomicrobia | Thermomicrobia | |
| Thermoproteota | Crenarchaeota |
Thermoprotei
cannot be used as the name of the class as it is on the list of nomina rejicienda (Opinion 79). Instead we propose Thermoprotea. As the name Crenarchaeota is widely used for the phylum, the Judicial Commission may consider conserving this name instead of Thermoproteota |
|
| Thermotogota | Thermotogae | Thermotogae | |
| Verrucomicrobiota | Verrucomicrobiae | Verrucomicrobia |
