Aulacoseira subborealis stat nov (Bacillariophyceae): a common but neglected plankton diatom
Aulacoseira subarctica f. subborealis differs from A. subarctica var. subarctica by a number of morphological features (smaller linking spines without areolae on their base, shorter spine grooves, discus always areolated, shallower mantle and different 'Formwechsel', considerably finer str...
