Scientific Description
Habit and structure. Thallus with primarily upright axes, red when pressed but often iridescent in situ. Primary axes compressed to flattened, percurrent, spathulate, to 1.6 mm broad medially then tapering to blunt apices, but with the apex of the primary filament emergent. Lateral branches arising from submarginal positions in an alternate pattern. Cortical cells in surface view in vaguely linear series, often sinuous, elongate, 70–100 µm long, 12–25 µm wide.
Reproduction. Tetrasporangia borne in short alternate lateral branches, adaxially and singly on radially elongate pericentral cells, thus in whorls of 5 sporangia, spherical, tetrahedrally divided, to 120 µm diam. Other reproductive structures not observed.
Distribution. Widespread in warmer waters of the Indo-Pacific.
