Cyclotella gamma


Cyclotella quillensis

LM scalebar = 10 µm = 80 pixels.


Contributor: Rex Lowe | Somayyeh Kheiri - April 2015
Diameter: 6.24-18.12 µm
Rows of areolae in 10 µm: 7-8 (chambered striae by circumference)


Valves are disc-shaped, with a narrow mantle. The valve face may be flat or transversely undulate. The central area is distinct and isolated from the marginal chambered striae. The central area covers 1⁄ 2 to 1⁄ 3 of the valve face. The central area contains 1-4 fultoportulae, which are distinct in LM. In the SEM, marginal fultoportulae are positioned on each costa. One to two rimoportulae are present near the valve margin, in line with a costa. Marginal spines may be present, positioned in line with each costa. The number of costae (interstriae) in 10 µm is 12-15.

Autecology Discussion

Cyclotella meneghiniana is wide spread and particularly common in shallow, nutrient rich waters.
