Asterionella: elongate cells which are joined at the base to form stellate colonies, (seen in valve view) basal pole of the cell typically wider than the apical pole Fairly large for planktonic <strong>diatoms</strong>, each cell 50-70 microns Commonly found in dense blooms during May, prior to the onset of thermal stratification
