Description
Thalli 30-40 cm tall, soft and felt-like, consisting of one or more rusty to rose-red, ligulate blades from a small discoid holdfast; blades 2-7 cm wide and simple, linear-lanceolate, gradually attenuated to a point, or forming marginal outgrowths up to 4-5 mm long, or proliferous, forming bladelets 3-10 cm long and 0.2-1 mm thick; stipitate, the stipe simple or forked, narrowly cuneate to slender and compressed; margins and surface of blades, except the base, covered more or less densely with small, spinose papillae; cortex 4-6 cell layers thick; medullary cells variable in size and shape, 1.5-16 µm in diameter. Cystocarps 300-500 µm in diameter, solitary and pedicellate in the superficial outgrowths that tend, in part, to be flattened or blade-like, or basal, two per papilla, on simple, narrow attenuated papillae; carposporeangia subspherical, 12-18 µm in diameter. Spermatangial sori superficial, indefinite on the bases and blades of slender, elongate papillae terminated by thin acute tips. Tetrasporangial sori small, 250-350 mm diameter, ellipsoidal, laterally positioned on elongate papillae; tetrasporangia 38-47 µm in diameter, forming linear rows 6-9 tetrasporangial cells long; released through a pore in the outer wall.

Habitat
Low intertidal to subtidal, associated with sand in moderately sheltered sites
