Hecatonema sargassicola   Borgesen,  1938 (Algae)
Organism information awaits expert curation
Class: Phaeophyceae

Size: Height 2 mm

Plants forming low, soft, dense expansion. Basal system composed of creeping filaments. More or less free or coherent near the edge, composed of irregular roundish-oval or irregular cells about 6-7 µ broad and upto 15 µ long and 7 µ high. Most of the erect filaments long, some remaining short, being composed of only one or few cells, the uppermost of these cells transformed into plurilocular sporangia. Long assimilating filaments up to 2 mm high and 6-7 µ broad, consisting of cells 10-20 µ long. Cells possessing one or more parietal, irregularly shaped chromatophores.

Plurilocular sporangia arising often from the base or generally from the middle of the assimilatory filaments; mostly pedicellate, sometimes sessile, pedicel composed of a single or 2-3 cells, generally unilaterally placed along the filament developed from nearly every cell. Sporangia sometimes irregularly alternate or scattered, oblong-oval in shaped, 10-13 µ long and 8-11 µ broad. Proliferation of the sporangia frequent, the walls of the earlier sporangia often found surrounding the last sporangium. Hairs absent.

Epiphytic on the leaves of Sargassum.
