• Notes:
  • Schlesner and Hirsch (1984) assigned this genus to the family "Planctomycetaceae". Publication: Schlesner H, Hirsch P. Assignment of ATCC 27377 to Pirella gen. nov. as Pirella staleyi comb. nov. Int. J. Syst. Bacteriol. 1984; 34:492-495.
  • For the type species of this genus another name is in use, which is affiliated with the genus Pirellula Schlesner and Hirsch 1987. Publication: Schlesner H, Hirsch P. Rejection of the genus name Pirella for pear-shaped budding bacteria and proposal to create the genus Pirellula gen. nov. Int. J. Syst. Bacteriol. 1987; 37:441.
  • This taxon name is occasionally misprinted in some sources as: "Pirellu".
  • The BRCs most frequently used for deposits in this group are: DSM: 3; ATCC: 2.
  • Later homonym of the fungal genus Pirella Bainier 1883; the name is illegitimate because of the precedence of a fungal genus. Publication: Schlesner H, Hirsch P. Rejection of the Genus Name Pirella for Pear-Shaped Budding Bacteria and Proposal to Create the Genus Pirellula gen. nov. Int J Syst Bacteriol 1987; 37:441-441.
  • Pittman et al. (1991) suggested the abbreviation "PIRL" 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.
  • The name Pirella is illegitimate because of precedence of the fungal genus Pirella Bainier 1883 [Rule 51b(4)]. Consequently, a new genus designation Pirellula has been proposed by Schlesner and Hirsch 1987. Publication: Schlesner H, Hirsch P. Rejection of the genus name Pirella for pear-shaped budding bacteria and proposal to create the genus Pirellula gen. nov. Int. J. Syst. Bacteriol. 1987; 37:441.
