Naded 282000: Branching filament, branch ends have a hair-like thread.
Naded 298000: Spherical shaped cell with two flagella. Cell diameter is about 6.4µm.
Naded 327087: Semicells are subcircular in shape and the cell wall has 14-16 undulations. Cell wall is smooth with a deep median constriction and narrow sinus. Cell length is 11.6µm and width is 10.5µm.
Naded 1110003: Vase shaped lorica with a smooth cell wall. Cell length is 20.2µm and width is 4.7µm.

Naded 444000: Cylindrical shaped filaments with plate-like chloroplast. Cell size varies.
Naded 444006: Cylindrical shaped filaments with plate-like chloroplast. Filaments are very thin (no more than 10µm wide) in comparison to Mougeotia sp.
Naded 455000: Cylindrical shaped filaments with net-like chloroplast. Cells enlarge towards cell junctions. Cell size varies.
Naded 897003: Cylindrical filament with constrictions at cell cross-walls. Cell ends do not tapper and are identical. Filament diameter is about 1.2µm.
Naded 510002: Cylindrical cells arranged latterly in a colony. Cells have no spikes or spines. Cell length is about 7.9µm and width is about 2.7µm.
Naded 510003: Cylindrical cells arranged latterly in a colony. Each cell has one curved apical spike on each end of the cells. Cell length is about 5.5µm and width is about 1.1µm.
Naded 528002: Ovate cells centered in a sheath.
Naded 536001: Cells have rounded angles with an open sinus and deep constriction. Cells are subquadrangular and have a flat apex. Cells are filamentous. Cell length is 8.5µm and width is 5.6µm.
Naded 948050: Cylindrical filament with heterocytes. Cells are constricted with no apparent sheath. Heterocytes are long and cylindrical. Filament width is about 2.5µm and heterocyte diameter is about 3.0µm.
