Taxonomic note
This species has only been collected in very shallow water. It was first collected on a marine rail at 10 to 20 cm depth on the west side of Magueyes Island, La Parguera. Subsequently it was collected at the same depth on rubble, stones and pieces of wood on a silty bottom beneath branches of the mangrove Rhizophora mangle L. approximately 100 m north from its original collection site. Plants are vesicular with vesicles occurring in clusters of two or three to many. The vesicles are somewhat irregular in shape, being nearly cylindrical to expanded above. They also range from being arcuate to nearly straight. Individual vesicles measure to 14 mm long and 0.3 to 0.4 mm diameter at their bases and to 2.6 mm at their broadest subapically. The vesicle bases are variably annularly constricted, the annulations being distinct in some plants and barely discernible in others. Vesicles are rarely branched, occasionally giving rise to another vesicle laterally from near the base. The clusters of vesicles are held together by common entangled rhizoids, 60 to 70 µm in diameter. Rhizoids issue from both the base of vesicles as well as from the lower annulated region. The rhizoids terminate in digital pads where they attach to the substratum. - (24 June 2012) - M.D. Guiry
