General Environment
This is a marine species.
Description
Thallus upright, to 10 cm high, anchored in
sandy substratum by a well-developed tuft of rhizoids, bright
green in colour; axes cylindrical, to 5 mm wide near the base,
gradually attenuating toward the apices, dichotomously to
somewhat irregularly branched, unconstricted; apices rounded.
Thalli composed of longitudinally arranged interwoven
and irregularly swollen medullary siphons, 50-110 µm wide,
giving rise to a single layer of peripheral utricles; utricles
polygonal in surface view, with a broadly rounded apex, distinctively broader than high in transverse
section, (143-) 248-310 (-365) µm in diameter and (177-)
187-215 (-225) µm high, adhering laterally to neighbouring
utricles except at the corners; utricle stipe eccentric. Chloroplasts and amyloplasts absent from utricles and confined to the medullary siphons. Reproductive structures
immersed in the thallus, produced laterally from medullary
siphons close to the base of the utricle stipe, spherical to
ellipsoidal in shape, 80-120 µm in diameter, lacking a basal
cross wall separating them from the rest of the thallus (Dawes & Mathieson 1972).
