• Emendations:
  • Kageyama and Benno 2000 Kageyama A, Benno Y. Emendation of genus Collinsella and proposal of Collinsella stercoris sp. nov. and Collinsella intestinalis sp. nov. Int J Syst Evol Microbiol 2000; 50:1767-1774. Anonymous. Notification list. Notification that new names and new combinations have appeared in volume 50, part 5 of the IJSEM. Int J Syst Evol Microbiol 2000; 50:1955.
    Notes:
    • ⊕ Emendation accompanied by the proposal of 2 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:
    • ⊕ Emendation accompanied by the proposal of 1 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. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated.
