Cosmarium fastidiosum  West & G.S. West

This species would seem to be genuinely rare. West & West (1908) only recorded it from a small pond in Oxfordshire. Its site preferences are not defined for Britain. For Europe, Tsarenko, et al. (2014) give "Planktonic, bethic in bogs, also in reservoirs; mesotrophic."
