• Notes:
  • 🧕 Komarek and Golubic (1990) assigned this genus to the family Dermocarpellaceae Ginsburg-Ardré ex Christensen 1978. Publication: Komarek J, Golubic S. Guide to the Nomenclature and formal taxonomic treatment of oxyphototroph prokaryotes (Cyanoprokaryotes). Unknown Publisher, Unknown City, 1990.
  • 🧕 Strunecky et al. (2023) assigned this genus to the family Pleurocapsaceae Geitler 1925. Publication: Strunecky O, Ivanova AP, Mares J. An updated classification of cyanobacterial orders and families based on phylogenomic and polyphasic analysis. J Phycol 2023; 59:12-51.
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Cyanocystis Borzì 1882. Publication: Komárek J, Anagnostidis K. Nomenclatural novelties in chroococcalean cyanoprokaryotes. Preslia, Praha 1995; 67:15-23.
  • ❗ Krkia is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🧍 According to Komarek and Golubic (1990) originally assigned to Cyanobacteria but unclearly described, probably synonym with Cyanocystis. Publication: Komarek J, Golubic S. Guide to the Nomenclature and formal taxonomic treatment of oxyphototroph prokaryotes (Cyanoprokaryotes). Unknown Publisher, Unknown City, 1990.
