BASIONYM: Nitzschia communis Rabenhorst 1860
LM scalebar = 10 µm = 80 pixels.
Observations
Contributor: Pat Kociolek - March 2011
Length Range: 25-40 µm
Width Range: 3-4 µm
Striae in 10 µm: 32-38
Description
Valves are linear with rounded apices. Fibula are relatively large and distinct, about 10-13 in 10 µm. Striae are resolved in the light microscope but very fine. Individual areolae within striae are not visible.

Valves linear with rounded apices. Fibulae are relatively large. Striae are fine and number 32-38 in 10 µm.
Compare
Nitzschia communis is quite readily identified by the shape of the valve, especially the broad apices. It might be confused with N. pusilla, which is shorter in length and has much finer striae, 43-55 in 10 µm (Krammer & Lange-Bertalot 1988). Nitzschia communis can be distinguished from N. minuta and N. palea with which is shares linear shape and fine striation, by its broadly rounded apices.
