Abstract
Abstract Gracilaria “verrucosa” is now regarded an invalid name, with G. gracilis being used in recent studies of the genus from the Russian coast of the East Sea (Sea of Japan). This has created nomenclatural confusion for members of the genus in this region. Here we revise the taxonomy of G. “verrucosa” from Peter the Great Bay (East Sea, Russia) based on morpho-anatomical characters and comparisons of nuclear small subunit rDNA, plastid rbcL and mitochondrial cox1 sequence data. No differences were found between sequences for attached and unattached forms of G. “verrucosa”. Molecular data also indicate that G. “verrucosa” from Peter the Great Bay is conspecific with Gracilaria vermiculophylla from the northwestern Pacific, and the Russian population is closely related to Korean-Japanese populations from the East Sea rather than with populations on the Pacific coast of Japan.
