Emendations:
- Zou et al. 2021 Zou Y, Lin X, Xue W, Tuo L, Chen MS, Chen XH, Sun CH, Li F, Liu SW, Dai Y, et al. Characterization and description of Faecalibacterium butyricigenerans sp. nov. and F. longum sp. nov., isolated from human faeces. Sci Rep 2021; 11:11340. Oren A, Garrity GM. List of changes in taxonomic opinion no. 35. Notification of changes in taxonomic opinion previously published outside the IJSEM. Int J Syst Evol Microbiol 2022; 72:5164.
  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. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. See the LPSN phylogeny page for details.
