Nomenclatural note
CAS: "Later homonym of Cotyledon Linnaeus 1753. Substitute name: Gutswinkiella De Toni 1894.  Three species are described in Brun 1891: Cotyledon circularis Brun, Cotyledon clypeolus Brun, Cotyledon (Cyclotella ?) coronalis Brun, no type is designated. Three species are included in De Toni 1894 (Gutswinkiella circularis, G. clypeolus, G.? coronalis) and G. clypeolus is designated as the type. Round, Crawford & Mann (1990) p. 687 incorrectly indicate that Van Heurck 1896 (ref. 000897), p. 519, designated Cotyledon circularis Brun 1891 as the lectotype. Van Heurck 1896 discusses genera Cotyledon Brun and Acanthodiscus Pantocsek, he includes in genus Acanthodiscus A. clypeolus (Brun) and A. rugosus Pantocsek and places C. coronalis Brun (and perhaps C. circularis) into a new genus Bruniella Van Heurck." - (27 October 2014) - M.D. Guiry
