Eunotia richbuttensis

 

Eunotia serra

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Paula Furey - March 2011
Length Range: 14-26 µm
Width Range: 2.7-3.6 µm
Striae in 10 µm: 19-20

Description

The ventral margin is only slightly concave to nearly straight. The dorsal margin is convex, with one hardly-visible central swelling. The apices are acutely rounded and very slightly delimited from the rest of the valve. The helictoglossae are not visible in the LM. The raphe curves on to the valve face. The striae are slightly radiate. The areolae are unresolved in the LM.
