内容記述（抄録等）
Results of the present writer's observations on vegetative propagation and spore germination of Distromium decumbens (OKAMURA) LEVRING (Phaeophyta, Dictyotaceae) in culture are reported herein.
Vegetative propagation occurs from frond margin and rhizoids but the latter case is more common. Secondary frond produces the secondary rhizoids which also produce tertiary fronds producing tertiary rhizoids. Spores of this alga germinate according to the same pattern as the one known in Dictyopteris prolifera (OKAMURA) OKAMURA, D. undulata HOLMES, Spathoglossum pacificum YENDO, Stypopodium zonale (LAMOUROUX) PAPENFUSS and Zonaria diesingiana J . AGARDH ．
