Abstract:
Distinctive features that support the retention of Lemmermann's genus Uroglenopsis and distinguish it from Ehrenberg's Uroglena are presented. In Uroglena, the cells are united by a branching system of cytoplasmic threads, which is produced as cells divide and separate, the cells have a pointed posterior end because of attenuation to the diameter of the connecting thread, and the whip flagellum is approximately one-half the length of the long pleuronematic flagellum. In Uroglenopsis, the cells are united by a branching system of gelatinous stalks, the cells are truncate at the posterior end, and the whip flagellum is at the most one-quarter the length of the long flagellum. A key to species is given and statospores of all species are illustrated. The close relationship of Skuja's Eusphaerella to these genera is explored.
