The ultrastructure of the flagellate Chrysochromulina spinifera (Fournier) comb. nov. (Prymnesiophyceae) with special reference to scale production

An investigation into the ultrastructure of Chrysocamponula spinifera Fournier is reported. Attention is drawn to the unusual method of production of the long spine scales and the marked similarity in cell structure between Chrysocampanula Fournier and Chrysochromulina Lackey. In view of their similarities Chrysocampanula spinifera Fournier has been transferred to Chrysochromulina Lackey as Chrysochromulina spinifera (Fournier) comb. nov.
