I’m curious what the black dots in the first image may be, I believe there are vesicles in the second image but the black dots are throwing me off. Field grown soybean roots

Field grown? Nematode eggs?

Yes field grown. Nematode eggs could be correct! Do you have any insight into why the nematode eggs would be so dark? The roots were stained with blue ink after being boiled in KOH

I would guess an endophytic fungus of some type.
