Morphology and segregative cell division were observed in Siphonocladus rigidus from Japan. Thallus formed cushions and filaments got tangled up. Segregative cell division occurred by the condensation of cell contents into the filament. Then constrictions appeared on the filament structure. The filament structure decreased in diameter at constrictions and separated into some protoplasts. Protoplasts enlarged and formed daughter cells.
