Taxonomic notes: Womersley (1979, p. 508) commented that this species is probably not a Polysiphonia, but generic placement depends on collections of fertile material. The thallus consists of long slender axes, possibly prostrate, bearing short, mostly unbranched laterals from each segment, spirally arranged with a divergence of 1/4; the axial segments have 4 pericentral cells, and are 100–120 µm in diameter with L/D 1.5–2.2, and the segments of laterals are 40–60 µm in diameter and L/D 1–1.5.

Species of uncertain status.
