Lindavia eriensis

LM scalebar = 10 µm = 80 pixels.

Rows of areolae in 10 µm: 16-20 based on circumferential density


Valves are disc shaped. The valve face is flat, and is often colliculate. A single, central fultoportula is located in the center valve, across the valve face from the single rimoportula. The rimoportula is located at the central end of a shortened stria. Alveolate striae extend 1/3 of the radius from the valve margin. The alveolate striae end irregularly, resulting in an irregularly shaped central area. Internal foramen of the striae are visible in larger specimens, near valve face margin. The alveolate striae occur 16-20 in 10 µm (total striae count vs valve circumference) or 17-22 in 10 µm (tangential chord count).

Autecology Discussion

Lindavia delicatula is a species found in the plankton of large lakes. It was found at greater than 5% abundance in the summer phytoplankton of the Laurentian Great Lakes (Barbiero and Tuchman 2001). It is typically found in conditions of low total phosphorus and low chloride, and its presence is indicative of pristine conditions, (Reavie and Kireta 2015).
