Ulotrichaceae is a family of green algae in the order Ulotrichales.^[1] Members of the family are found in both marine and freshwater habitats.^[2]

Members of the family Ulotrichaceae consist of unbranched filaments. The cells are typically barrel-shaped or cylindrical, wider than long. The cell has a chloroplast which forms a girdle-shaped parietal band; each chloroplast may have several pyrenoids.^[2]

Asexual reproduction occurs via fragmentation of the filament, or the production of zoospores. Sexual reproduction is isogamous, and involves an alternation of generations between the larger, filamentous gametophyte and a Codiolum-stage sporophyte.^[2]
