Two New Records of Marine Algae Phyllodictyon anastomosans and Saccharina ochotensis from Korea

摘要

Phyllodictyon anastomosans (Harvey) Kraft et M.J. Wynne and Saccharina ochotensis (Miyabe) E.E. Lane C. Mayes, Druehl et G.W. Saunders are first recorded in Korea. A pantropical green alga, P. anastomosans was collected on a rock wall in the subtitalzone of Jeju Island. This species has very tiny fan-shaped and netted thalli that are green in color. A cold temperate brown alga, P. ochotensis has very thick and leathery thalli that are deep brown in color. Morphological characteistics and habitats ofthese species are described with taxonomic accounts.
