Note that Fragilaria radians was formerly known as Fragilaria gracilis! Please do not mix up Fragilaria radians ("finer striae", around 20 striae per 10 micrometers) with Fragilaria radians coll. (aggregate group, "coarser striae"; species include e.g. F. fragilarioides and F. radiantifalsa). Note that F. radians in Finland is not as common as earlier thought (when the name F. gracilis was used); please see other possibilities, such as F. acerosa and F. neglecta, which are likely more common in Nordic countries.
