Kobayasiella subtilissima (Cleve) Lange-Bertalot (Figs 2 AC-AO; 6A-F) Iconographia Diatomologica 6: 268 (Lange-Bertalot 1999). — Navicula subtilissima Cleve, Actas Societas Pro Fauna et Flora Fennica 8 (2): 37 (Cleve 1891). ECOLOGY AND DISTRIBUTION. — Kobayasiella subtilissima was found in 29 lakes in this study. However, it was present in low relative abundances (mean 1.1%) with a maximum of 10.7% in Lake 18-R. This species was more common in acidic conditions (Appendix 3) with a pH optimum of 6.2 and a relatively low DIC optimum of 0.76 mg /L (Appendix 4). A globally distributed species under consistent environmental conditions. DESCRIPTION The frustules are rectangular and narrow in girdle view. The valves exhibit a linear-elliptic to linear-lanceolate shape with subcapitate to capitate ends. Based on a sample size of 22, the valve dimensions range from a length of 25 to 32.5 µm and a width of 5.5 to 6.5 µm. The length-to-width ratio is 4.3 to 5.0.The stria density ranges from 36 to 40 in 10 µm.
