Taxa Notes:
Naded 261000: Spindle shaped cells either in a colony or solitary. Cell ends tapper. Cell length is 24.8µm and width is 1.0µm.
Naded 316058: Cell slightly curved with broadly truncate poles. Cell length is 112.9µm and width is 8.7µm. Cell is 13 times longer than broad.
Naded 455000: Cylindrical shaped filaments with net-like chloroplast. Cells enlarge towards cell junctions. Cell size varies.
Naded 510001: Cylindrical cells arranged latterly in a colony. Outer cells in colony have two long spikes. Cell length is about 9.2µm and width is about 3.5µm.
Naded 510002: Cylindrical cells arranged latterly in a colony. Cells have no spikes or spines. Cell length is about 5.5- 6.6µm and width is about 1.5-2.0µm.
Naded 510005: Cylindrical cells arranged latterly in a colony. Outer cells in colony have two long spikes and inner cells have smaller apical spikes. Cell length is about 4.5µm and width is about 1.0µm.
Naded 510006: Cylindrical cells arranged latterly in a colony. Cells are curved with sharply pointed apices. Cell length is about 4.5- 10.9µm and width is about 1.1-1.5µm.
