[segment L:B c. 1], attached by branched multicellular rhizoids, these with a single primary cell cutting off 6–9 radiating dichotomously branched arms. Lateral branches to 75 µm diam. [segment L:B 0.5–1], determinate and simple or with 1 or 2 laterals. Trichoblasts to 650 µm long, when young secundly branched, but appearing dichotomous when mature; basal 1 or 2 cells equidimensional, more distal cells progressively narrower and more elongate.
Reproduction. Reproductive structures not observed.
