Plants less than 30 cm long and soft; thallus repeatedly branched in all directions, cylindrical or compressed with narrow branchlets as much as 40cm long, light green in colour, plants grow first attached to the substratum but later become free floating; cells of the thallus more or less quadrangular in shape with a single cup shaped chloroplast; pyrenoids 3 to 4.

This species forms tufts, bright green, composed of branched axes, which can reach several centimeters long (20-30 cm). The main axis and branches are covered with conical branchlets very characteristic.
