Diagnosis | Thalli consist of many terete branches, tapering to acute tips, densely covered with 1 to 8 mm long spinose determinate branchlets arranged in whorls, forming distinct nodes and internodes at the distal portions of the branches. Cross-section of a branch reveals a dense core of thick-walled and very small rhizoidal cells. Thalli up to 30 cm in height (Ref. 80758). The fusion of branches upon coming in contact with each other and their ability to form secondary holdfasts at tips of branches results in the formation of thick and strongly attached clumps or carpet-like beds (Ref. 80758). |
