Cyclotella meneghiniana was collected from an artificial pond Kosharskij near Feodosia, Crimea, isolated and cultured under different conditions (freshwater, 2‰, 4‰, 8‰, and 16‰ salinity). Detailed light- and electron microscope investigations were made of specimens from monoclonal cultures of C. meneghiniana and comparisons made with type material of both C. meneghiniana and C. kuetzingiana, which are conspecific. Cells cultured under different salinity conditions were very similar, showing only slight differences in the number of valve face fultoportulae, in the pattern of the satellite pores of the mantle fultoportulae, and in the lengths of the striae. New cultures started from single initial cells isolated from 3 of the 4 monoclonal cultures at 8‰or 16‰ salinity conditions, and grown in 16‰ salinity showed greater morphological variability, with differences in the pattern and number of the marginal striae, the number and placement of valve face fultoportulae, and the pattern of the satellite pores of...
