Kryptoperidinium foliaceum (F. Stein) Lindemann ( Figures 15–20)

Cells were pale brown in colour with a red eye spot and a central nucleus ( Figures 15 and 16). Cells were 30–50 µm long and 28–45 µm wide. Cells were strongly dorso-ventrally flattened and broadly circular in dorsal view ( Figures 15 and 16). The cingulum was median and not offset ( Figure 15). Cells had very thin thecae on which it was very difficult to discern any thecal tabulation ( Figure 17) although it has been reported by Figueroa et al. (2009). Cysts were formed within our cultures – these were ovoid to spherical in dorsal view ( Figure 18) and narrowly elliptical in apical view ( Figures 19 and 20). Two strains from the Caspian were successfully sequenced which match those for Kryptoperidinium foliaceum ( Figure 32).
