Description
Thalli 6-12 cm high, cartilaginous, yellowish
to brownish red or purplish black, forming stiff, densely
branched clumps arising from a discoid holdfast that is
stoloniferous at the base; erect shoots terete to
compressed, 1-2 mm wide, typically branched at the base
with long axes that are either simple or once or twice forked
above, vegetative axes naked, becoming densely crowded
on all sides above by short, branched ramuli or bladelets in
fertile thalli; cortex of 7-8 layers of cells, medullary cells
variable in size and shape, 1.5-17 mm diameter. Cystocarps
papillate, 665-875 µm in diameter, borne in bladelets on
crowded simple or 1-2 times forked branchlets in the
upper third of the axis, and naked or armed with short spines
around the ostiole; carpospores subspherical,
15-25 mm in diameter. Spermatangial plants feathery, with
distichously branched or flattened ramuli that appear
echinate. Tetrasporangial sori 140-280 µm in
diameter, irregularly distributed on 2-3 times distichously
divided branchlets; tetrasporangia narrow, ellipsoidal,
12-15 µm broad by 22-30 mm long, formed in
chains 4-6 cells long.
Habitat
Saxicolous, exposed to surf and swift flowing currents
often forming an extensive turf in the mid-low intertidal.
