Taxa Notes:
 
Naded 282000: Branching filament, branch ends have a hair-like thread.
Naded 316012: Cell strongly curved with acutely pointed poles. Cell length ranges from 26.7-29.1µm and width ranges from 4.9-6.3µm.
Naded 316026: Cell is strongly curved with sharply rounded poles. Cell length ranges from 65.8µm and width ranges from 9.0-10.2µm. Cell is 6.7-7.0 times longer than broad.
Naded 852002: Filament incased in a sheath with cells that are wider than broad. Filaments are attached to substrate and ends tapper. Filament width is about 3.3µm.
Naded 444000: Cylindrical shaped filaments with plate-like chloroplast. Cell size varies.
Naded 890025: Cylindrical shaped filament in a sheath with cells longer than broad. Filament ends do not tapper and are broadly rounded. Filament width is about 4.2µm.
Naded 538009: Semicells are triangular shaped in end view and cells are twisted at isthmus. Sinus is open and cell wall is granular. Cell width is about 9.4µm.
Naded 582000: Cylindrical shaped cells in a filament. Cells have two plastids with large pyrenoid at center of radiating short branches in stellate pattern
