Gomphonema pseudopusillum Reichardt ( Figs 88–106 View FIGURES 88–118 )
Valves heteropolar, clavate, gibbous and biconstricted. Headpole is cuneate, basal part is elongately cuneate, gradually narrowing to the footpole, usually with almost straight margins. Apical inflations are slightly wider than the middle one or have the same breadth. Marginal undulations are strongly evident. Length: 20–34 μm, breadth: 5.7–6.7 μm. Striae parallel to slightly radiate in center, more strongly radiate at the footpole, 11–13 in 10 μm. Axial area distinct, narrow. Central area small, one or two striae in central part are shorter. Stigma isolated and distinct.
Observations: —This population is smaller than Reichardts’s images of G. pseudopusillum type population. However, the images shown by Reichardt represent only a portion of the size diminution series.
