  • 🥇 Nomenclatural type of the genus Rhodococcoides Val-Calvo and Vázquez-Boland 2024. Publication: Val-Calvo J, Vazquez-Boland JA. Mycobacteriales taxonomy using network analysis-aided, context-uniform phylogenomic approach for non-subjective genus demarcation. mBio 2023; 14:e0220723.
  • ⏰ According to Klatte et al. (1994), this species is an earlier heterotypic synonym of Rhodococcus luteus (ex Söhngen 1913) Nesterenko et al. 1982. Publication: Klatte S, Jahnke KD, Kroppenstedt RM, Rainey F, Stackebrandt E. Rhodococcus luteus is a later subjective synonym of Rhodococcus fascians. Int. J. Syst. Bacteriol. 1994; 44:627-630.
  • ❗ Rhodococcoides fascians 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 Rhodococcoides.
