本文首次报道了两种来自日本的红藻：Chondracanthus saundersii C.W. Schneider & C.E. Lane （Gigartinaceae, Gigartinales）和Schottera koreana M.S. Calderon， T.H. Seo & S.M. Boo （Phyllophoraceae, Gigartinales）。在日本鹿儿岛县马之岛近海35 m处采集了一种桑氏c.s haundersii标本。桑氏C.的rbcL和COI - 5P （cox1）序列与来自百慕大的模式标本和来自古巴和巴西的其他标本形成了一个分支。从形态学上看，桑氏线虫的特征是存在次级附着物，被压缩成宽度达1毫米的扁平轴，以及较松散的髓质。在日本千叶县大原和爱媛县松山的潮间带至潮下水域采集了2个韩国海螺标本。韩国种rbcL序列与韩国报道的标本（包括模式标本）序列密切相关。形态上，韩国的特点是单细胞的无色毛从皮质细胞发育而来。
We report two red algal species, Chondracanthus saundersii C.W. Schneider & C.E. Lane (Gigartinaceae, Gigartinales) and Schottera koreana M.S. Calderon, T.H. Seo & S.M. Boo (Phyllophoraceae, Gigartinales), from Japan for the first time based on molecular and morphological analyses. A C. saundersii specimen was collected at a depth of 35 m offshore of Mageshima Island, Kagoshima Prefecture, Japan. The rbcL and COI‐5P (cox1) sequences of C. saundersii form a clade with the type specimen from Bermuda and additional specimens from Cuba and Brazil. Morphologically, C. saundersii is characterized by the presence of secondary attachments, compressed to flattened axes up to 1 mm in width, and a looser medulla. Two specimens of S. koreana were collected in lower intertidal to subtidal waters at Ohara, Chiba Prefecture, and Matsuyama, Ehime Prefecture, Japan. The rbcL sequences of S. koreana were closely related to reported sequences of specimens from South Korea including the type specimens. Morphologically, S. koreana is characterized by the presence of unicellular colorless hair developed from cortical cells.
