Excellent!
What is the refractive sphere in the center of the body?

Nice one! It looks like P suecicus, even though I do expect the pellicle to be more strongly ornamented with the 100x objective.

Best wishes, Rene.

Has a smooth surface is rather Phacus orbicularis

Very nice. You even got a trace of the cilia. My vote is Phacus pleuronectes because the large central body (paramylum) is distinct and the chloroplasts are in longitudinal rows. My reference is How to Know the Protozoa (Jahn, Bovee & Jahn).
