Description
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.
