Morphological and molecular characterization of three new Azadinium species (Amphidomataceae, Dinophyceae) from the Irminger Sea
Some species of planktonic Azadinium produce azaspiracids (AZAs), a group of lipophilic phycotoxins causing human poisoning after mussel consumption. We describe three new species from the North Atlantic, all of which shared the same Kofoidean plate pattern characteristic for Azadinium: Po, cp, X, 4...
