This species has a very fine aerolation. It can be distinguished from other species by the central hyaline area and the hyaline lines radiating from it between the areolae. It also has a distinctive shape in girdle view. The valve is very high (often higher than wide) and the valve margin appears to undulate slightly.

Optical section (girdle view) of the pennate diatom, Cymatopleura solea (Brébisson) W. Smith 1851. Valves are elliptical with a central waist and bluntly pointed apices. The valve surface is marked with several transverse undulations best seen in girdle view (seen well in this image). Striae and undulations are not interrupted in the median axis. Raphe are marginal. Very short costations appear as beading around the edge of the valve. The central nucleus is seen in this image. There is a single lobulated plastid one half of which lies along the inner surface of the epivalve and the other along the inner surface of the hypovalve. Collected from the benthos of a freshwater pond near Boise, Idaho, January 2005. DIC.

Pad of connecting mucilage is clearly visible. Scale bar indicates 100 µm. The image was built up using several photomicrographic frames with manual stacking technique. Sample from North Sea near Heligoland (Aufwuchs on red alga Ceramium spec.).

Phaeoschizochlamys (fay-owe-shit-sew-clam-ees), (pheothamniophyte), cells with golden plastids enclosed in mucus and forming aggregates. The mother cell wall is cast off in two halves (hemispheres) during cell division, and frequently these old walls are visible in the colony matrix. Differential interference microscopy.
