Diameter: 7.5-14 µm
Mantle Height: 5.5-14 µm
Rows of areolae in 10 µm: 15-17 based on circumferential density
Valves are disc-shaped, with a tangentially undulate valve face. The central area is slightly asymmetric. In LM, the raised portion of the central area is convex and, generally, lacks ornamentation. The depressed portion of the central area is concave and is colliculate, and includes central strutted processes. One to three rimoportulae are present at the end of shortened striae near the raised portion of the valve face. Alveolate striae cover about 1/3 diameter of the valve face. Typically, shorter striae are associated with the raised side of the valve face, and longer striae are associated with the depressed side of the valve face. Striae are alveolate and are composed of multiseriate rows of two different sized areolae. Larger areolae border each stria and are arranged opposite. Between the larger areola rows are smaller areolae, which are arranged in single rows near the center of the valve and bi- to multiseriate near the margin. The alveolate striae occur 15-18 in 10 μm based on a tangential chord count (15-17 in 10 μm based on circumference). Internal foramina are visible in larger specimens. Spines were not observed.
Several species of Cyclotella have tangentially undulate central areas and should be compared with L. michiganiana.
Basionym: Cyclotella michiganiana
Author: Skvortzow 1937
Diameter: 5.0-20.4 µm
Rows of areolae in 10 µm: 15-18
Valvis diametro 0.0050 ad 0.0204 millimetrum metientibus; striis marginalibus distinctis, in duabus zonis radiantibus, circiter 15 ad 18 in 0.01 millimetro; aculeolis nullis; area centrali hyalina, irregulariter punctata, punctis nonnullis uno loco validioribus. Hab., in aquis lacus Michigan prope Chicago-Plate I, Fig 3, 10, 18. Frustule in the middle depressed and undulate. Valve circular, separated into two areas: the central area with a diameter of one-half that of the valve, at one side covered with large beads irregularly disposed, and the marginal area composed of one or two zones of radiating striae and a robust marginal rim. Valve diameter 0.0050-0.0204 mm. Striae 15-18 in 0.01mm. -Common in the collection. This species differs from C. striata and its varieties in its coarser striae and in the minute size of the valve. It differs from C. cassia in the nature of its central area. Both of these related species are reported from brackish waters.

Lindavia michiganiana is an indicator of oligotrophic lakes (Stoermer et al. 1983, Pappas and Stoermer 1995), with a TP optimum of 10 ug/L (Cumming et al. 1995). The taxon is more often found in the pelagic zone rather than in littoral or riparian areas (Reavie and Smol 1998, Reavie and Kireta 2015). Lindavia michiganiana has been reported from British Columbia (as C. michiganiana; Cumming et al. 1995), the Laurentian Great Lakes (as C. michiganiana; Stoermer and Yang 1969, Reavie and Kireta 2015), the Adirondacks (as C. michiganiana; Camburn and Charles 2000), and boreal lakes in Quebec (as C. michiganiana; Fallu et al. 2000), along with occasional reports from streams in North America.
