I don’t think that’s a root.

It looks more like the sterile base of a Pisolithus, which is more closely related to truffles and puffballs.

If you look at the 3rd picture, in the lower left part, You can see where I pulled it away from what seemed to me to be a tree root.

although may be associated with a root in a mycorrhizal association. Phaeolus is a saprophyte, which means there would have to be dead wood nearby. No indication of that in the original description.
