Sphingobacteria Cavalier-Smith, 1987[1]

The FCB group is a superphylum of bacteria named after the main member phyla Fibrobacterota, Chlorobiota, and Bacteroidota. The members are considered to form a clade due to a number of conserved signature indels.[2]

Cavalier-Smith calls the equivalent grouping a phylum by the name of Sphingobacteria. It contains the classes Chlorobiota, Fibrobacterota, Bacteroidota, and Flavobacteria. However, this megaclassification is not followed by the larger scientific community.[3][4][5]

An analogous situation is seen with the PVC group/Planctobacteria.

The Bacteroidota–Chlorobiota group in brown is visible on this 2016 tree of life using ribosomal protein sequences[14]
