Diagnostic features

Unbranched filamentous chlorophyte with generally short cells, each of which has a parietal band-like chloroplast wrapped around most of the interior cell surface, containing numerous pyrenoids. Germination of zoosporangia is sometimes observed in collected material, producing numerous small zoospores, each with 4 flagella, per cell (cf. Klebsormidium, in which this is very rarely seen, and results in a single biflagellate zoospore per sporangium). Ulothrix also lacks the elbow-structures with mucilage pads found in Klebsormidium.
