    Notes:
    • ⊕ Emendation accompanied by the proposal of 4 new species in the genus.
    • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details.

• Notes:
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Planctomicro"; "Planktomicrobium".
  • 🎰 The BRCs most frequently used for deposits in this group are: KCTC: 4; DSM: 4; VKM: 1; CECT: 1.
