Count Notes:

  Comments: Sample contains a lot of sediment and is dominated by diatoms. Two plamer cells were counted.
Taxa Notes:
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 in comparison to Mougeotia sp.
Naded 455000: Cylindrical shaped filaments with net-like chloroplast. Cells enlarge towards cell junctions. Cell size varies.
Naded 890025: Cylindrical shaped filament with a thin sheath and isodiametric cells. Filament diameter is about 3.6µm.
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 538005: Cells have deep median constriction with an open sinus. Semicells are elliptic with narrowly rounded apical angles. Semicells are triangular in end view. Cell length is about 16.0µm and width is about 15.0µm.
Naded 852004: Filaments are incased in a sheath. Filaments are attached to substrate and have tapered ends. Filament width is about 1.4µm.
