Objective : The purpose of this dissertation is to make a list of the Rhodophyta growing naturally in the Korean coastal waters, and to carry out a survey on the current distribution status to investigate the Bangiaceae which can be used as medicinal herbs. Methods : References and research papers about herbology published at home and abroad were examined. Results : A list was made about Bangiaceae plant which were cultivated or grew naturally in Korea, after investigated the data on domestic and foreign Bangiaceae plants. Out of those lists, serviceable plants were selected , their distributions were analysed. 1. A total of 2 genera and 18 species of Bangiaceae were found in the Korean coastal waters among which 1 genera and 4 species(approximately 22%) were medicinal plants. 2. Out of the 18 species of Bangiaceae 16 species belonged to Porphyra, and out of the 4 species of medicinal plants 4 species belonged to Porphyra. 3. Among the medicinal parts 4 species belonged to algae species had cold property, and had salty and sweet flavors. 4. 4 species had the efficacy of Lung, Spleen and bladder meridian had the potency of soften hardness, which helps to remove hard clots generated, cure phlegm in human body. 5. No toxic drugs were detected. Conclusion : There were totaled to 18 genera and 2 species in Bangiaceae in Korea and among them medicinal plants are 1 genera, 4 species, some 22% in total.

Foliose species of the Bangiaceae (Porphyra s. l.) are very important in Korean fisheries, and their taxonomy and ecophysiology have received much attention because of the potential for developing or improving aquaculture techniques. Although 20 species of foliose Bangiales have been listed from the Korean coast, some of them remain uncertain and need further comparative morphological studies with molecular comparison. In this study, we confirm the distribution of four Pyropia species from the east coast of Korea, Pyropia kinositae, P. moriensis, P. onoi, and P. retorta sp. nov., based on morphology and rbcL sequence data. Although P. onoi was listed in North Korea in old floral works, its occurrence on the east coast of South Korea is first revealed in this study based on molecular data. P. kinositae and P. moriensis, which were originally described from Hokkaido, Japan, are first reported on the east coast of Korea in this study. Pyropia retorta sp. nov. and P. yezonesis share a similar thallus color and narrow spermatangial patches in the upper portion of the frond, and they have a sympatric distribution. However, P. retorta can be distinguished by the curled or twisted thalli and by molecular data. The biogeographic pattern of the two native species, P. kinositae and P. retorta, suggests that the east coast of Korea may have been a place of refugia during the Last Glacial Maximum (LGM), and then recolonized to the northern part of Japan through the restored East Korean Warm Current after the LGM.

Neoporphyra kitoi Ma. Abe, N. Kikuchi, Tamaki, Tom. Sato, Murase, Fujiyoshi & Mas. Kobayashi has been known as an endemic species in Japan. Its high temperature tolerance suggests that it could be advantageous for cultivation. In this study, we collected it from the Ulleungdo island, Korea and transferred it into Pyropia for a new combination, identified as Pyropia kitoi(Ma. Abe, N. Kikuchi, Tamaki, Tom. Sato, Murase, Fujiyoshi & Mas. Kobayashi) D.J. Kim, T.O. Cho & B.Y. Won comb. nov. based on morphological and molecular analyses. Pyropia kitoi is also reported as a new record species in the list of Korean macroalgal flora. Although we didn't observe the emergence of new blades from the rhizoidal cells, which is a key character for this species, our molecular analysis of rbcL revealed that our samples from Korea were congruent with "Neoporphyra kitoi" from Japan and were nested within the clade of Pyropia. The gene sequence divergence between the Korean and Japanese samples was 0-0.2%.
