Ulotrichales is an order of green algae in the class Ulvophyceae.[2] Members of this order are most common in freshwater and marine habitats, although some are terrestrial or aerophytic.[3]
Algae in the Ulotrichales are diverse in morphology, and include coccoid (round single cells), sarcinoid (three-dimensional packet-like), filamentous (thread-like), and blade-like forms. The cells generally contain a single parietal chloroplast with one to several pyrenoids, and one or several nuclei.[3]
Some algae in the Ulotrichales are diplohaplontic; in these algae the gametophyte stage is dominant and the sporophyte consists of a single club-shaped to spherical, attached zygote. This zygote is known as the Codiolum stage.[3] In other Ulotrichales, sexual reproduction is unknown.[3]
