由Kamptner(1954，p.23，74，75)描述的球石科环球藻属包括两个包含种：Coccosphaera letopora Murray&Blackman，1898和Umbilicosphaera mirabilis Lohmann，1902，这两个种均未被指定为模式种。随后，纤毛虫被指定为模式种(Hay&Towe，1963，第502页)。然而，根据《国际植物命名法》的规定，由于奇异Umbilicosphaera是Umbilicosphaera的单型模式种，所以最初对环球菌属的界定包括先前属的模式种，因此是一个多余的名称
THE coccolithophorid genus Cyclococcolithus was described by Kamptner (1954, p. 23, 74, 75) with two included species, Coccosphaera leptopora Murray & Blackman, 1898, and Umbilicosphaera mirabilis Lohmann, 1902, neither of which was designated as type species. Subsequently C. leptopora was designated as the type species (Hay & Towe, 1963, p. 502). However, because Umbilicosphaera mirabilis was the type species of Umbilicosphaera by monotypy, the original circumscription of Cyclococcolithus included the type species of a prior genus and was therefore a superfluous name, according to the provisions of the International Code of Botanical Nomenclature
