The hierachical rank of Laurenc ia complex was changed recently and divided into three genera, Chondrophycus, Laurencia and Osmundea. This alga, Chondrophycus intermedius (Yamada) Garbary et Harper distributes mainly along the coasts of East Asia Pacific. The other distributions in other places are also given. In China, ever as Laurencia intermedia, it was described insufficiently, or reported erroneously or mixed up with Chondrophycus palisades (Yamada) K. W. Nam (original L. palisada) and Chondrophycus capituliform is (Yamada) Garbary et Harper (original L.capituliformis). Some questions need to be clarified. Its morphology and anatomy from China coasts specimens are observed in detail with a lot of figures, and compared with other related species. As a distinct species, it differs from C.palisadus (Yamada) K. W. Nam and C.capituliform is (Yamada) Garbary et Harper in the physical characteristics such as sticking to the paper, the shape of cystocarp and the arrangement of superficial cells, and so on. Some questionable distributions are discussed.
