Status of Name

Type Information
Type locality: Wright Canyon, Sodwana Bay, northern Kwazulu-Natal, South Africa; (De Clerck & al. 2008: 228) Holotype: H. Verbruggen and T. Schils; 7 November 2003; -33 m on slope; GENT; KZN-b 2281 (De Clerck & al. 2008: 228) Notes: See Coppejans et al. (2005, as Pseudocodium floridanum) for an in situ photograph of the type.
Description
Thallus upright, to 2 cm high, anchored in sandy substrate by basal, branched, multicellular rhizoids, bright green in colour; axes compressed, 1 mm
wide and 300-350 µm thick, two to four times dichotomously branched, hardly tapering toward the apices, lacking constrictions; apices truncate with a depressed apical pit. Thalli composed of longitudinally arranged, interwoven, irregularly swollen medullary siphons, 20-60 µm wide, giving rise to a single layer of peripheral utricles; utricles polygonal in surface view, with a flat apex, approximately isodiametric in transverse section, (71-) 80-88 (-101) mm in diameter and (104) 112-123 (126) µm high, laterally adhering except at the
corners; utricle stipe not eccentric. Chloroplasts and amyloplasts at least in living plants present in the utricles and siphons. Reproductive structures immersed in the thallus, produced laterally from medullary siphons close
to the base of the utricle stipe, variable in morphology, ranging from spherical on a gradually broadening stipe to irregular, broadly clavate structures, 80-90 mm wide and 120-185 µm long, lacking a basal cross wall separating it from the rest of the thallus, opening distally by an undifferentiated pore.
Habitat
So far only known from Sodwana Bay, South Africa, where it is confined to deep water (below -30 m depth). The species is rather common, growing on coarse sand and coral debris
