  • was originally classified as the deepest branching member of the phylum (high-G+C, Gram-positive bacteria) based on 16S rRNA gene comparative analysis. However, the analysis lacked suitable outgroups, and additional 16S rRNA gene sequences indicate that it is most closely related to , which it also resembles phenotypically. Furthermore, both species are reproducibly affiliated with the phylum (green non-sulfur bacteria), despite currently being classified in its own phylum, the . Transfer of to the class , and transfer of the class to the phylum , are proposed. Descriptions for the phylum and the class are emended to reflect the proposed changes in classification.
