* Dictyota coriacea (Holmes) I.K. Kwang, Hy. S. Kim & W.J. Lee, 2004

Japanese name: サナダグサ (sanadagusa)

Basionym: Glossophora coriacea Holmes, 1896

Heterotypic synonym: Pachydictyon coriaceum (Holmes) Okamura, 1899

Type locality: —Enoura, Japan

Description and remarks: —Specimens are dark brown, erect, up to 5–13 cm tall with rhizoidal holdfasts. The dichotomously branched apices may bend inwards, causing an overlap between adjacent branches. One specimen shows multi-proliferous branching on one side of an apical branch, possibly due to physical damage, as shown in ( Hwang et al. 2004b). This species is common throughout the study sites in spring, often growing together with Colpomenia sinuosa and Dictyopteris spp.
