  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. Validation list no. 207. List of new names and new combinations previously effectively, but not validly, published. Int J Syst Evol Microbiol 2022; 72:5517.
  • 😩 Deposit incorrectly indicated in some sources as representing the type strain of this taxon: NBRC 100776.
  • ❗ Streptomyces hygroscopicus subsp. sporocinereus is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Streptomyces hygroscopicus within a separate genus Streptomyces.
