Taxonomy
Kingdom:Chromista
Phylum:Ochrophyta
Class: Phaeophyceae
Order:Scytosiphonales
Family:Scytosiphonaceae

Description
Color: Light brown

Thallus form and type: Branched and tubular tufts

Substratum: Intertidal rocks

Occurrence: Mid littoral zone, tide pools, wave exposed rocks

Season: November-April


Plants forming very intricate tufts; height 6 cm, width 8 mm; irregularly ramified branches felted together, probably growing together now and then. Thallus compressed with uneven surface; plant body free floating; branches pseudodichotomus, narrow with sharp tips. Mature thalli hollow, near the cavity cells large on the peripheral small cells, covered with a layer of small, polygonal cells about 13 µ broad, containing a disc-shaped, roundish or slightly lobed chromatophore. Hairs either scattered or present in small groups, but not densely crowded and sterile part of the thallus.

Plates bearing plurilocular sporangia, the latter clavate, several together in circular to oval sori, spread over the whole surface of the thallus, 16 µ long and 6-7 µ broad.

A chaetophoracean alga Phaeophila dendroides lives endophytically in the plant body of Rosenvingea intricata.
