Description
Thallus small, 1–2 cm high, growing as a dense tuft, erect branches rising from compressed creeping axes, attached to the substratum by peg-like holdfasts. Erect axes compressed, 316–389 µm broad, 100– 166 µm thick; more densely branched on the middle to upper parts (or rarely on branchlets) for one half their lengths, with branches 3–5 (-9) times palmate, apex obtuse and often broken, slightly constricted at base; rarely proliferous from surface; purple red, cartilaginous. Transverse section creeping stem 132–145 µm broad, 165–224 µm thick, consisting of a medulla of irregularly angular parenchymatous cells, 11–20 ?m × 8–13 µm, one layer of smaller cortical cells, 7–9 × 4–7 µm; transverse section erect axes consist of a medulla of irregularly angular parenchymatous cells, 10–17 × 7–13 µm, with one layer of smaller cortical cells, 7–10 × 4–6 µm, rare rhizoidal filaments found within two edges of compressed medullary tissue. Cystocarps unilateral, prominently protruding, triangular, 290 µm high, 422 µm broad, rostrate, unconstricted at base; gonimoblast consisting of few small cells, chains of carposporangia radiating from a core of gonimoblast filaments surrounding the central axis, carposporangia obovate, 17–26 × 8–10 µm, pericarp 53–59 µm thick, consisting of 5-8 layers of cells, some inner cells elongated, extending to the placenta. Tetrasporangia and spermatangia unknown.
