Compressed perennial stalk (stipe) with blunt teeth, arising from simple disc-conical holdfast. Lower branches (perennial laterals) arise in a radial pattern and are narrowly divided in an even pattern (pinnate) and have a thickened mid rib. Multiple and sometimes branched stems (stipes) are angular and arise radially from the perennial stalk. Secondary laterals (upper laterals/ramuli) are multiply divided and fine. Vesicles (when reproductive) are very small, attached by a short stem (petiole), and have either no protrusion (mucro) or a slender protrusion. Medium brown. Up to 50 cm long (thallus).
This species has been renamed from Sargassum to Phyllotricha.
