(Polyblepharidaceae); four belong to the Chrysophyceae, Chromulina pleiades n.sp. (Chromulinaceae), Isochrysis galbana n.g., n.sp., Dicrateria inornata n.g., n.sp., D. gilva n.g., n.sp. (Isochrysidaceae); and one belongs to the Cryptophyceae, Hemiselmis rufescens n.g., n.sp. (Nephroselmidaceae).A form of reproduction in a palmelloid phase, not previously described, is recorded for the Isochrysidaceae.
