EDIT: was "Unknown, ID help please"
In my freshwater sample. Moved faster than Amoeba on same slide but much slower than ciliates on same slide.
Appeared to be a sphere with a hollow center; surface bumpy but vacuoles present; did not see any vacuoles contracting.
Oly 40x S Plan + 1.25x intermediate lens+ 2.5x relay lens, DIC; single frames.

Hi Ferry,
Yours sounds like an accurate ID/description.
No cilia, no flagella, no membranous shell.
The slide mount was deep, i.e., cover glass was not squashing anything. Possible (likely?) that this ball was simply drifting in the water.
The granular structure does look a lot similar to a live amoeboid on the same slide.
Same microscope setup; single frames.

These are pictures of Mayorella spec. Notice the paired crystals, which are typical for some species like Mayorella bigemma (bi-gemma = two stones)! The crystals are hour-glass-shaped and attached to spherical bodies. The right picture shows the nucleus very clearly, just right of the green algae.
