Filaments free or in fascicles, sometimes densely coiled, prostrate or with erect branches, solitary or geminate falsely-branched. Branching initiates after trichome dissociation following the formation of necridic cells, typically between two adjacent heterocytes, usually not at heterocytes, loop-like lateral formations may occur after which the tops of the trichomes later divide. Trichomes isopolar, cylindrical, uniseriate, constricted at the cross walls; terminal parts of branches cylindrical or slightly widened, with rounded apical cell; middle parts of trichomes sometimes with elongated, cylindrical cells. Sheaths firm, limited, parallel or diverging, lamellated, usually yellow-brown, coloured by scytonemin, particularly in mature filaments. Cells pale or olive-green, usually with solitary, irregularly disposed granules or with granular content, rarely yellowish or pinkish coloured; apical cells sometimes vacuolate. Heterocytes intercalary, solitary, rarely in pairs, cylindrical or barrel-shaped. Akinetes not produced. Cells divide crosswise to the trichome axis, mainly in meristematic zones near the ends of branches. Reproduction by hormogonia, which develop at the ends of branches and liberate from the sheaths.</paragraph>
