Scientific Description
Habit and structure. Thallus deep red, with prostrate and sparsely branched erect axes. Prostrate axes 75–100 µm diam. [segment L:B 1–2], attached by pit-connected rhizoids arising from the proximal end of pericentral cells. Erect axes to 3.5 mm tall, simple or with lateral branches separated by 11 or 12 segments; lower axes 70–100 µm diam. [segment L:B 1–2], tapering gradually to 50–60 µm diam. near apices [segment L:B 0.5–1.5]. Lateral branches replacing trichoblasts. Structure with 4 pericentral cells and 1 trichoblast or scar cell every 2 or 3 segments in a spiral pattern.
Reproduction. Reproductive structures not observed.
Distribution. Known from warmer waters of the eastern Indian and central and western Pacific Oceans. In north-western Australia it is known from the Dampier Archipelago and Cassini Island.
