Rack ur brain - Image Challenge 4

A 28-year-old man complained of gastrointestinal pain and bloating. At the request of his health care provider, he submitted a fecal specimen preserved in low viscosity polyvinyl alcohol (LV-PVA). A trichrome stained smear was made from some of the specimen. Microscopic observation shows an object, measuring 10 to 12 micrometers at its greatest diameter that was seen in low numbers on the slide.

What is your diagnosis? Based on what criteria?

Ditto. Looks like pollen. Not a parasite.
