I was about to photograph a live Closterium (a desmid) when I applied a little too much pressure on the coverslip. The cell wall ruptured and all the contents flowed out leaving a transparent cell; actually 2 hemicells joined centrally.
These images show the brownish cell walls lined with longitudinal striations and some girdle bands.

Thanks, René: I have looked at a lot of live Closterium and also had never seen the cell wall in such detail. I think my clumsy mounting turned out to be an advantage.

Thanks Rich & David.
I don't recall ever seeing such marked longitudinal striations and girdle bands in live specimens; may have been very lucky with this species.
