Description
Thallus foliose, red to dark brown, soft and gelatinous in texture, arising from a small discoid holdfast up to 15 cm high and usually cosisting of three to five (-10) simple linear to lanceolate blades 8-15 cm long and 2-3 cm wide, which often bear marginal, lanceolate bladelets 5-25 mm long by 3-5 mm wide from the upper and basal parts; cortex 8-11 layers, the cells moniliform or polygonal to stellate in shape; medulla filamentous with the filaments lax. Tetrasporophytes and gametophytes isomorphic, the gametophytes dioecious with reproductive structures scattered over the entire blade except the basal parts. Tetrasporangia initiated from inner cortical cells, cruciately divided when mature, 42-60 microns long by 15-22 microns wide. Spermatangial mother cells transformed from surface cells, cutting off spermatangia transversely and terminally. Carposporangial ampullae not seen; auxiliary cell ampullae abundant, composed of three orders of ampullar filaments (6-12 cells long) initiated from a subbasal inner cortical cell, with the auxiliary cell being the basal cell of the third-order filament cut off from the first cell of the second-order ampullar filament. After diploidization, the ampullar filaments branching laterally three to four times to form a basal cluster surrounding the gonimoblasts during cystocarp development; mature carposporangia-bearing gonimoblasts immersed inside the medulla and surrounded by branched ampullar filaments and a network of secondary medullary filaments.
