Diagnosis	Thallus green to brownish red, usually bent, club-shaped, attached to substrate by a small rhizoidal holdfast. Cross section of thallus shows a cylindrical axial filament extending almost the whole length of the thallus. Successive whorls of lateral branches cover the thallus, each whorl consisting of 24 to 28 primary lateral branches, slightly expanded at their distal ends and giving rise to 4 to 7 short capitate branchlets laterally coherent forming a monostromatic cortex. Cortical cells polygonal in surface view. Each primary lateral branch with 4 or more aplanosporangia, 150 to 190 μm in diameter and containing 2 to 9 oval or spherical aplanospores, 70 to 80 μm in diameter. Thallus up to 5 cm in height (Ref. 80758).
