Cladophora rudolphiana (C. Agardh) Kützing, 1843:268; Collins, 1909b:336; Setchell and Gardner, 1920b:218; Dawson, 1944:209; Dawson, 1957b:8; Dawson, 1961b:378; González-González et al., 1996:131.

Cladophora gracilis sensu Doty, 1947:23; Dawson, 1961b:377; Sakai, 1964:33–38 [non Cladophora gracilis Kützing, 1845:763 (note that Cladophora gracilis (A. W. Griffiths ex Mackay) Kützing, 1845:215 is nom. illeg. since the basionym Conferva gracilis A. W. Griffiths ex Harvey, 1835:304 is also nom. illeg. as it is a later homonym of Conferva gracilis Wulfen, 1803:21; thus, the correct new name is Cladophora gracilis Kützing, 1845:763, which is now a synonym of Cladophora flexuosa (O. F. Müller) Kützing, 1843:270; basionym: Conferva flexuosa O. F. Müller, 1782: 5, pl. 882 (see Söderström, 1963, 1965; Bot et al., 1989; Silva et al., 1996a; van den Hoek and Chihara, 2000:164)].
