Filaments planktonic; trichomes solitary or rarely in small floccose clusters, c-shaped curved, sigmoidally coiled or irregularly circular, not constricted at the cross walls. Vegetative cells cylindrical, 1.5–2.5 × longer than broad, 2–4.5 μm broad, blue-green, with aerotopes. Apical cells elongated and sharply pointed. Akinetes intercalary, barrel-shaped or bluntly cylindrical oval, sometimes slightly curved, single or multiple in series, 10–16 μm long × 3.5–5.5 μm broad, with smooth, colourless epispore.
Specimens examined:—Lake Clarendon, Eungella Dam, Wuruma Dam.
Other records:— Queensland: SE Queensland, McLeod (1975).
Observations:—Cosmopolitan. Uncommon species, rarely reported from reservoirs and weir pools. Differs from R. mediterranea by the curved shape of the trichome.
