General Environment
This is a marine species.
Description
Plants saxicolous, erect, to 13 cm in height, axes gelatinous, terete, to 5 mm in diameter, irregularly radially branched to five orders, non annulate. Axial cells without crystals. Rhizoidal filaments to 20 microns in diameter, producing terminal adventitious cortical fascicles. Cortical fascicles flexuous, subalternately and dichotomously branched; outer cortical cells cylindrical. Gametophytes dioecious. Spermatangia forming dense paniculate clusters on terminal or subterminal cortical cells. Carpogonial and auxiliary-cell distinct filaments without a thick mucilage coat. Generative auxiliary cell distinct by shape and size before fusion with connecting filament. Cystocarps subsphaerical, loosely constructed, to 240 microns in diameter, not cleft, Carposporangia obovoid, 14-24 microns in diameter. Tetrasporophytes unknown.
Habitat
Grows on cobbles lacking perennial vegetation at depths of 3-7 m. It is a spring annual in areas of moderate water movement and is probably subject to sand abrasion during storm periods.
