Did the subject eat crayfish? These are compatible in morphology with Psorospermium hackeli.

A case of "pseudoparasitosis" in O&P exam, Beaver bodies!Algae Psorospermium, following consumption of seafood crayfish!
They are not parasites. They look like algae, diatoms maybe.

Desmids?
Alghe Diatomee
"Beaver bodies". Algae that can be found in faeces after the consumption of crayfish. Object not a parasite.
Agree with the Psorospermium. You can see the plates of the outer shell and it is currently undifferentiated. It appears to be the north American long form.
Non-parasite
