Description
Color: Yellowish green

Thallus form and type: Grape-like vesicles

Substratum: Intertidal rocks, corraline stones, dead corals

Occurrence: Infra littoral fringe, rock pools

Season: November-April

Plant erect, miniature balloon-like, occurring in smaller or larger clusters attached to the substratum. Thalli up to 5 cm, usually connected with each other in the same tuft by separate, rhizoidal hapterons, younger thalli club shaped but older ones enlarged in the upper portions, becoming sacciform, with annular constrictions at the base. Rhizoids septate, horizontal and in continuation with the erect portion. Number of vesicles proliferating from the basal rhizoidal branches resulting in dense clusters of vesicles of different ages and sizes and shapes, 25-50 mm long, 10-20 mm broad. Vesicles forming plenty of cysts inside. Cysts growing into new plants under favorable conditions.

Reproduction by cysts and by numerous 4 ciliated motile spores formed inside each vesicles, escaping through large number of rounded apertures on the wall of the vesicle. Sexual reproduction not known.
