Abstract: Taxonomic account is given to the seven species of the Dictyotaceae, Dictyopteris divaricata (Okamura) Okamura, Dictyota dichotoma (Hudson) Lamouroux, Pachydictyon coriaceum (Holm.) Okamura, Padina arborescens Holmes, P. crassa Yamada, Spatoglossum paciflcum Yendo, and Zonaria diesingiana J. Agardh, collected from Ullungdo Island, Korea. Dictyopteris divaricata is distinguished that it has larger, broader and less undulated thallus. Dictyota dichotoma shows much morphological variation according to growing season. Pachydictyon coriaceum is characterized by dichotomous branch, two cell layered cortex and one large rolled medulla. Padina arborescens is distinguished by dark, hard and rarely lobed thallus and has eight to nine medullary cells. P. crassa is characterized by light brown, much lobed thallus and four to six celled medulla. Spatoglossum pacificum has variation in globs morphology according to season. Zomaria diesingiana has much lobed thallus and greenish brown, exuberant fibrous protuberance looks like midribs from cortex in basal part of thallus.
