Looks like A. Caesarea but since the volva is lacking it might be A. parcivolvat and it is a common eastern species. The fact that you found it near ariver bank makes me think that also. I have seen This same fungi growing near the river bank on the New River in West Virginia.

No obvious saclike volva

The white is stipe interior where it was broken, not a saclike volva.
I dug around the base and did not see any evidence of a volva.

Cap margin.

No striations on the cap margin, also no yellow gills, I do not think this is in the caesarea group.

Is that a sac like volva in the 3rd pic? Its hard to tell if that is the base were you broke/cut it or a volva.
