Molecular probes were developed for the dinoflagellate genus Azadinium to discriminate\udamong three taxa difficult to differentiate by light microscopy. This\udgenus contains azaspiracid toxin-producing Azadinium spinosum, but also non-toxigenic\udspecies. Quantitative polymerase chain reaction (qPCR) and fluorescence in\udsitu hybridization (FISH) assays were applied to cultured isolates and Azadiniumspiked\udfield plankton. Molecular methods were highly specific and sensitive in the\udunambiguous detection of Azadinium, and thus are valuable for routine plankton,\udbiogeographic and phylogenetic investigations.\u
