  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Chamaesipnhonophyceae"; "Chamamiplmnophyceae".
  • ❗ Chamaesiphonophyceae is the correct name instead if this class is regarded as a separate class (i.e., if its nomenclatural type is not assigned to another class whose name is validly published, legitimate and not rejected and has priority).
