Notes:
- According to Rong and Huang (2010), this species is a later heterotypic synonym of Streptomyces anulatus (Beijerinck 1912) Waksman 1953 (Approved Lists 1980). Publication: Rong X, Huang Y. Taxonomic evaluation of the Streptomyces griseus clade using multilocus sequence analysis and DNA-DNA hybridization, with proposal to combine 29 species and three subspecies as 11 genomic species. Int J Syst Evol Microbiol 2010; 60:696-703.
- Streptomyces praecox is the correct name if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Streptomyces.
