Earlier identified as Fragilaria gracilis, which is actually not that common in Finland (no certain observations due to confusions in taxonomy and identifications). Fragilaria acerosa has a length of 13-70 μm, width of 1.5-2.5 μm and 18-22 striae per 10 μm. Please note also a similar species Fragilaria neglecta.
