Hi Olivier,

Haven't seen you around here in a while!

Very nice specimens and photographs. The "rotata" is always a special treat to see.

Hi Charles,
thanks for comment.
the discover of such a biotope near home boost my microscopy observations.
more Micrasterias:
the first is likely M.crux-melitensis, but not sure...

Hi,
it's not M.crux,but M.rotata again.
the last one, M.jenneri is quite rare in Europe.
best regards

Please don't stop -- I like these last two best of all. :D

The oblique lighting gives such a nice 3D appearance.

Are these single shots, or stacked?

That sure is a nice spot for microbe hunting. There will be many other interesting algae, protists and micro animals.

I don't think that is M crux melitensis. It looks like an anomality. I hope you can find one. Micrasterias jenneri is something special. It always looks a bit battered. I suspect it is has a wild character. :)
