Achnanthes minutissima var. saprophila has pronounced large central area on rapheless valve. This form might have been lumped into Achnanthidiu, minutissimum before?
Also differenciation beween Navicula tenelloides and N. suchtlandii or N. longicephala in prevoius counts should be studied.
Diatom concentration on slide is low, sparse, diatoms often clumped together , makes count difficult!
