L. comensis
-
Cells are 5-12 µm in diameter. Rows of striae 9-12 per 10 µm at the circumference.
-
Central ornamentation varies from star-shaped to irregular, and striae are variable in length.
-
Valve faces are slightly curved at edges, flat at the center.

L. ocellata
-
Cells are 3.7 - 15 µm in diameter. Rows of striae are 15-30 per 10 µm at circumference.
-
Central area takes up 1/3 to 2/3 of the valve face, and has 2-6 distinct depressions
-
Striae end irregularly at the central end

L. rossii
-
Cells are 6.3 - 16.5 µm in diameter. Rows of striae are 20-22 per 10 µm along the circumference.
-
Striae end irregularly at the central end.
-
Ornamentation on the central area of the valve face is variable in its grouping and areolae size: the photos here show linear organization, but ornamentation may also be more scattered.
