What are the round nodules?

I was doing some weed pulling in my garden a few weeks ago and pulled out this bunch of roots. Was wondering if someone can tell me what the round nodules are on the roots?

I believe those are called ground"pearls" it is a type of scale insect.

Nematoads?

Eat one you wimp, pretty sure just peanuts (evil laugh hahahaha)....

It's normal for certain classes of plants. They are part of the system for converting nitrogen into a form usable by the plant.
