Ten taxa of the genus Spirogyra (Zygnemataceae, Chlorophyta) in Korea were examined for morphology and taxonomic category with field as well as cultured materials: S. africana (Fritsch) Czurda, S. decimina (Muller) Kutzing, S. distenta Transeau, S. dubia Kutzing, S. ellipsospora Transeau, S. ellipsospora var. crassoidea Transeau, S. gracilis (Hassall) Kutzing, S. submajuscula Kutzing, S. peipingensis Jao and S. variformis Transeau. Features of vegetative cell and female gametangium, shape of septum, chloroplast number, sexuality, size and shape of zygospore, and ornamentation of spore wall were major characteristics used for determination of the species. All of them were described for the first time in Korea.
