  • Silva (1980) notes that as circumscribed in the Index Nominum Genericorum, this family includes Beckia, the type of Beckiaceae Elenkin 1933; Coelosphaerium, the type of Coelosphaeriaceae Elenkin 1933; Gloeocapsa Kützing 1843, the type of Gloeocapsaceae Elenkin 1933; Gomphosphaeria, the type of Gomphosphaeriaceae Elenkin 1933; Holopedium (Lagerheim) Lagerheim 1893, a superfluous name for Microcrocis P. Richter 1892 and the type of the family name Holopediaceae Elenkin 1933, which is not in accordance with the rules of the ICN; Merismopedia, the type of Merismopediaceae Elenkin 1933; Microcystis Lemmermann 1907, the type of Microcystaceae Elenkin 1933; Pleurococcus, the type of Pleurococcaceae (Klebs) Warming 1890; and Woronichinia, the type of Woronichiniaceae Elenkin 1933. According to Silva (1980) Pleurococcaceae is traditionally and erroneously applied to Chlorophyceae because of a misinterpretation of Pleurococcus. Publication: Silva PC.
