Dinophysis diegensis Kofoid is a life history stage of Dinophysis caudata Kent (Dinophyceae, Dinophysiales)
Several species of Dinophysis Ehrenb. have been observed to produce “small cells” that are different in size and shape from the vegetative cells, following a reductionary division under certain environmental conditions, as part of a polymorphic life cycle. Based on observations on fixed field sample...
