Two species of Apoglossum is newly recorded in Korea collected from subtidal habitats of Jeju Island. Apoglossum minimum Yamada has previously been known only from the coast of Japan. It is characterized by having corticated midrib but lacking microscopic veins. Apoglossum gregarium (Dawson) Wynne is reported for the first time from the north western coast of Pacific Ocean. It has been distinguished by its ecorticate midrib from the former species. Their morphological characteristics in detail and taxonomic issues are discussed.
