Description
Color: Light green

Thallus is fan shaped, moderately calcified, solitary with a short thick attaching portion expanding immediately into flat strap shaped blades, often lobed, strongly zonate, distinguishable into light and dark zones, flexible, well calcified, attached to the substratum by means of an elongated, bulbous, root mass. Stipe cylindrical, about 3 cm long, 4 mm diameter, dilated above and greatly expanded to a broad flabellum. The flabellum about 10 cm high, 15 cm broad, irregularly split into several segments. The frond composed internally of pluriseriate filaments, very firmly coherent into a firm cortex. The corticating filaments 25-45 µm in diameter, densely branched, with numerous irregularly placed lateral appendages pedicellate, densely and fasciculately or cymoidly branched and terminating in truncate or dactyline apieces. Blade siphons constrictions above infrequent dichotomies absent or slightly symmetrical; lateral appendages irregularly spaced, long stemmed, dichotomously branched, apices crowded, short, rounded.
