Nomenclatural notes
Cited as "Closterium ehrenbergii var. percrassum (Borge) Grönblad 1920 in Prescott, Croasdale & Vinyard (1975: 50) but Grönblad (1920: 17) has "forma percrassa" [percrassum] nob[is] and cites a figure in Borge, not a name. Accordingly, the name is to be referred solely to Grönblad and the figure in Borge could serve as an icontype. - (20 Dec 2016) - M.D. Guiry

As "var. percrassum" in some lists (e.g., Prescott, Croasdale & Vinyard, 1975; Medvedeva & Nikulina 2014). - (20 Dec 2016) - M.D. Guiry
