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