Origin of Species Name
Adjective (Latin), serrated, saw-edged with teeth pointing forwards (Stearn 1983).
Description
Thalli 14-30 cm high, consisting of few to
many coarse, cartilaginous, dark purplish red shoots from
a crustose stoloniferous base; erect
shoots usually greater than 2 mm in diameter, terete
throughout, usually forked once or twice 4-9 cm above
the base into several main branches that are irregularly
dichotomously to oppositely branched 2-4 more times;
lower axes naked; upper branches provided on all sides at
more or less regular intervals with simple or branched
fructiferous ramuli of variable thickness; cortex 7-8 cell
layers thick; medullary cells variable in size and shape, 1.5-
17 µm in width. Cystocarps 400-700 µm in diameter,
mostly forming dense pedicellate clusters at intervals on
lateral branches; carpospores 12-18 µm in
diameter. Spermatangial plants sparsely branched, lacking
papillae, gracilariod in appearance. Tetrasporangial
sori 150-300 µm in diameter, widely scattered in ramuli
that point upward; tetrasporangia 32-41 µm
diameter, formed in chains 5-7cells long.
Habitat
Saxicolous in low intertidal in swift flowing currents near the entrance of bays.
