Origin of species name
Adjective (Latin), bearing corymbs.
This is a marine species.
Thalli 20-40 cm tall, crisp, yellowish-pink or pink to bluish-red, consisting of one to many blades from a stout discoid holdfast; blades 20-30 cm broad, simple, broadly obovate with a rounded apex or sometimes irregularly split or truncate, generally entire; stipe short, cylindrical, usually simple, lacking bladelets, merging gradually into a prominent coriaceous, cuneate, concavoconvex apophysis 7-19 cm long; fertile blade rounded at the apex, with the fertile portion papillate, 0.4-2.2 mm thick; cortex 6-8 cell layers thick; medullary cells variable in size and shape, 1.5-25 µm in diameter. Cystocarps 0.8-1.2 mm in diameter, usually 2-3 in corymbose papillae on margins and surfaces of the blade; carpospores subspherical, 13-17 µm in diameter. Spermatangial sori superficial, forming indefinite, irregularly anastomosing patches on the thallus surface or borne on thin, crisped triangular-shaped papillae with attenuated tips. Tetrasporangial sori 200-325 µm in diameter, in soral patches circling the base of slightly elevated, irregular to oblong mound shaped papillae; tetrasporangia 31-42 µm in diameter, in chains 6-8 cells long.
Exposed and sheltered habitats in the low intertidal.
