Taxonomic re-evaluation of Ericiolus and Mercedesia (Prymnesiophyceae) and description of three new species
The genera Ericiolus and Mercedesia are distinctive extant coccolithophores that are characterized by monothecate, monomorphic coccospheres with one type of triradiate star-shaped nannoliths. The two genera were described from the Danish coastal waters, the surface waters of the Arctic, and the Sout...
