General Environment
This is a marine species.
Description
Thallus medium to dark red to red-brown, fading to grey-red, (10-) 20-40 cm high, soft and mucilaginous, complanately branched with flat, irregularly pinnate branches for 3 or 4 orders, main branches (3) 6-10 mm broad, bearing marginal pinnate branches 3-10 cm long and also simple branchlets 3-10 mm long, with ultimate branchlets 1-2 mm broad; compact, rounded, potentially adhesive, discs 23 mm across, terminate few to numerous branchlets. Holdfast discoid, with adhesions also by the discs of dense, elongate cells; usually epiphytic on sea-grasses or larger algae, or epilithic (?). Structure multiaxial, developing a cortex 50-90 µm thick of slender branched filaments 5-8 cells long, with the lower 2-3 cells irregular, 5-10 µm broad, and the upper 3-5 cells ovoid, 2-3 µm in diameter, arising from the lax inner cortex of ovoid cells 15-25 µm in diameter. Medulla 35 cells thick, cells large, ovoid, 60-200 (250) µm in diameter, with frequent secondary pit-connections. Hairs on outer cortical cells common. Rhodoplasts discoid to elongate in cortical cells, ribbon like in medullary cells.
Habitat
Usually epiphytic on seagrasses (Womersley 1996: 98).
