    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. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details.

• Notes:
  • 🧕 Goodfellow and Williams (1983) assigned this genus to the uncategorized "Maduromycetes" Goodfellow and Williams 1983. Publication: Goodfellow M, Williams ST. Ecology of actinomycetes. Annu Rev Microbiol 1983; 37:189-216.
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Aficrobispora"; "Jficrobispora"; "Mcrobspora"; "Micfobispofa"; "Micmbispora"; "Micobispora"; "Micorbispora"; "Micrabispora"; "Micrebispora"; "Micrnbispora"; "Microbiospora"; "Microbispaora"; "Microbispoa"; "Microbispoba"; "Microbisporaa"; "Microbispqra"; "Microbispum"; "Microhispora"; "Miernbispora"; "Mierobispora"; "Mlcrobispora".
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Zhao et al. (2020), Muangham and Duangmal (2021). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • 🎰 The BRCs most frequently used for deposits in this group are: NBRC: 21; DSM: 20; JCM: 18; IFO: 15; ATCC: 13; NRRL: 9; CGMCC: 7; VKM: 4; KCTC: 3; CIP: 2.
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "ATCC PTA-5024: 1 Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
  • 🧍 Pittman et al. (1991) suggested the abbreviation "MBSO" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM. Codes and abbreviations for approved of effectively published names of genera of bacteria published from January 1980 to December 1990. Int J Syst Bacteriol 1991; 41:571-579.
