Scientific Description
Habit and structure. Thallus forming clusters of erect stipitate fronds from an emergent holdfast, olive to brownish green, to 6 cm tall. Stipes 5–10 mm long, 2–3 mm wide, mostly unbranched, each bearing a thin, spongy to firm, subcuneate, reniform or subcircular blade that is faintly zonate near the margins (more noticeable in wet material), 20–30 mm tall and up to 45 mm wide, composed of tightly woven siphons. Internal siphons cylindrical, 12–30 μm diam., sparingly dichotomously branched, with shallow elongate constrictions at the dichotomies, tapering to 5–10 μm diam. towards the surface and becoming tortuous, occasionally subtorulose, forming a pseudocortex; apices rounded. Siphons with numerous subspherical plastids 3–5 μm diam., each with a prominent pyrenoid.
Distribution. Known only from the Dampier Archipelago, One Arm Point and Cockatoo Island, northern W.A.
Habitat. Epilithic in the intertidal and shallow subtidal.
