Closterium subulatum (Kützing) Brébisson
Reference: Růžička 1977
Remarks: Basionym: Stauroceras subulatum Kützing. The original diagnosis of Kutzing 1849 is very poor, so the concept of Růžička is followed here, but he states that the cells are at most 21x longer than they are wide. This not the case with the specimens depicted below that has ratios between 22 and 31.
