Bacteriological Code and rank "Phylum"
The International Code of Nomenclature of Bacteria (1990 Revision) does not recognize any rank higher than Class (Rule 5b) and the names of phyla are not to be regarded as having been validly published even though they may have been published in a validation or notification list, or in the Approved List of Bacterial Names.
