Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 0.2 cm TL male/unsexed; (Ref. 82093)
Thalli to 2 mm high consisting of unbranched erect axes, that arise mainly from a single point or from a creeping filament. Axes are somewhat clavate, measuring 90-100 μm wide near the base, 140-170 μm in the middle part of the thallus, ending abruptly in an attenuate apex. Axial cells are lenticular, usually wider than long except near the base. A total of 8 periaxial cells are present per segment, each producing 2 anterior and 2 posterior cortical initials of cortical filaments. Anterior initials cut off 1-2 acropetal filaments, which are up to 2 cells long. Posterior initials either remain undivided or produce a single basipetal filament. Cortication remains incomplete, but adjacent cortical bands may be nearly confluent. Tetrasporangia form in distinctive whorls, are slightly protruding and measure 28-35 μm in diameter. Gametangia were not observed (Ref. 82093).
Typically, C. cingulatum has erect axes in the terminal parts or produces erect branches (Ref. 82093).
