Being an amateur diatomist, I use currently various reference books (see Bibliography)
for diatom systematics, but, living in a small village in western
Brittany, I have difficulties to consult recent publications and books.
So 
 
    - At the present time, I have been unable to name several species that I have observed,
 
  - The names that I have used for some
species likely are not up to date, but rather they correspond to
obsolete ones.
