Cells of this monotypic genus are solitary, elongate—fusiform, and strongly curved (lunate), resembling some species of Closterium. One of the ways that we can tell they are closely related to plants is they share the same photosynthetic pigments -- chlorophylls a and b -- and so have the same familiar green glow. Occasionally there are two chloroplasts per semicell. Desmids (e.g., Cosmarium, Closterium) are also common, as are epiphytes (e.g., Gomphonema, Coconeis) of water willow and some of the larger filamentous algae (e.g., Cladophora).
