Kelli and I say Hookworm, most likely, but possibly Trichostrongylus. Could also be, maybe, Ascaris that has lost its mammillated layer?
I am voting for a fertile, but decorticated Ascaris egg. Maybe the NEJM video from last week's post was a prelude to this image...
I would suggest a morel or other mushroom spore given the lack of internal differentiation usually seen with hookworm eggs at the time of passage.
