Notes:
- ⏲ According to Tamura et al. (2008), this species is a later heterotypic synonym of Streptomyces niveus Smith et al. 1956 (Approved Lists 1980). Publication: Tamura T, Ishida Y, Otoguro M, Hatano K, Labeda D, Price NP, Suzuki K. Reclassification of Streptomyces caeruleus as a synonym of Actinoalloteichus cyanogriseus and reclassification of Streptomyces spheroides and Streptomyces laceyi as later synonyms of Streptomyces niveus. Int J Syst Evol Microbiol 2008; 58:2812-2814.
- ❗ Streptomyces spheroides is the correct name instead 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.
