The Dinoflagellate <i>Gonyaulax fragilis</i> Is ‘the Wrong Man’ of the Dirty Seas, and Reinstatement of <i>Steiniella</i> Within the Protoceratiaceae (Dinophyceae) Open
The production of mucilage aggregates is commonly associated with diatoms, but the harmful events known as ‘ mare sporco ’ or dirty seas have been attributed to the dinoflagellate Gonyaulax fragilis or G. hyalina . The synonymy of these ta…
