  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Oxyophotobacteria".
  • 🧍 Illegitimate according to Tindall (2014): "Neither of the names of these [type] orders has been validly published under the International Code of Nomenclature of Bacteria (Lapage et al., 1992), nor have the genus names on which they are based been validly published.".

  • 🧍 The order Chroococcales Cavalier-Smith was validly published in 2002. However, this order is illegitimate because its type genus "Chroococcus" is not validly published under the Rules of the Bacteriological Code (1990 Revision).

  • 🧍 Irregularly formed name (not formed from the stem of the name of the nomenclatural type). According to the List Editor of the IJSEM, the type order, "Chroococcales", has been previously established by Gibbons and Murray. However, the type order "Chroococcales" Gibbons and Murray is not validly published. Publication: Anonymous. Validation list no. 25.
