Psammodictyon
- Valves constricted or panduriform
- Raphe eccentric
- Longitudinal undulation on valve face
- Fibulae bifurcated by central nodule

As in other nitzschoid genera, Psammodictyon posseses an eccentric, keeled, fibulate raphe system. Fibulae are bifurcated by a central nodule. Striae are...
