Thalli are to 4 cm high, pinkish-red in colour and composed of 4-5 gelatinous lobes, which are attached to a conspicuously cartilaginous, annulate stalk. The stalk is usually simple but may branch twice in well-developed specimens. The lobes are undivided and are broadly rounded, measuring approximately 1 cm in diameter and 3 cm in length. The thallus is multiaxial, composed of a filamentous medulla and cortex embedded in a gelatinous matrix. The distal ends of the cortical filaments produce the gelatinous matrix. Specimens were completely sterile (Ref. 82093).
Growing epilithically at a depth of 20 m in northern Kwazulu-Natal, South Africa (Ref. 82093)
