  • ❗ Nitrososphaerota is the correct name instead if this phylum is regarded as a separate phylum (i.e., if its nomenclatural type is not assigned to another phylum whose name is validly published, legitimate and not rejected and has priority).
  • ✏ The authority of the taxon name (Brochier Armanet et al.) deliberately differs from the authors of the publication (Oren and Garrity).
