Navicula vulpina
Kützing 1844 Category: Symmetrical biraphid
BASIONYM: Navicula vulpina Kützing 1844
LM scalebar = 10 µm = 40 pixels.
Observations
Contributor: Pat Kociolek - March 2011
Length Range: 85-110 µm
Width Range: 17-19 µm
Striae in 10 µm: 5-6 at the center, 6-8 at the ends
Description
Valves are lanceolate, with apices are broadly rounded, but not protracted. The axial area is narrow and straight, widening to form a rounded to sometimes nearly rectangular central area. The raphe is straight and filiform, with external proximal raphe ends dilated slightly and rounded. Distal raphe ends are hook-like. Striae are distinctly lineate and radiate along most of the valve, becoming parallel to convergent at the apices.

Due to its large size and coarse structure, this species is distinct from other members of the Lineolatae group of Navicula.

December 18, 2012 - Correction to basionym
The basionym was incorrectly listed as Pinnularia peregrina Ehrenberg. It was corrected to N. vulpina Kützing and the INA and CAS links were also corrected. - S. Spaulding
