EDIT: was Desmid ID ?
Collected from a lake outlet. Is this a Staurastrum sp.?
Another active swimmer (drifter?), appears to be surrounded with a mucilaginous matrix.
Quite a deep 3-dimensional alga. Each half has 12 projections: 2 pointing upwards and 2 pointing outwards (these 4 repeated on the lower surface), plus 4 sticking straight out from the circumference.
BHS 40x SPlan Apo. 2.5x photoeyepiece; 33 frames @0.002 mm, ZS PMax stack; single flash.

I checked the WWW and Xanthidium seemed a good match.
Ernst: most grateful for that positive ID.
I have just started looking at pond water and am amazed/intrigued by the number and variety of organisms in just a jar of water.
Looks like years of study ahead of me.
