Diagnosis | Greenish brown, erect and bushy thalli attached by a discoid holdfast to the substrate. Branching alternate-dichotomous, forming rounded axils. Branches strap-shaped, 2.5 to 10 mm across, broadest just below the forking, narrowest at the terminal portions. Segments between the dichotomies decrease in length from base to the distal end of the thallus. Apices of terminal segments rounded to obtuse when young, dentate or aculeate when mature. Outer margins of blades entire. Thalli up to 15 cm in height (Ref. 80758). |
