It has been 55 years since Hugo Freudenthal described Symbiodinium microadriaticum (Dinophyceae), the type species of this large and important dinoflagellate genus found commonly in mutualistic symbiosis with cnidarians, other invertebrates, and certain protists. However, no type specimen was designated by Freudenthal, thus S. microadriaticum was invalid, as was Symbiodinium and every species subsequently assigned to the genus. The original culture was lost, but since 1979, a different culture, CCMP 2464/rt‐061, had been considered to represent S. microadriaticum . From this culture, a preserved specimen is herein designated the holotype of S. microadriaticum , validating the binomial and Symbiodinium . All binary designations previously considered to belong in Symbiodinium also are validated herein.
