yes going by photos in mo it looks alot like Volvariella,gloiocephala,smaller specimens in the same local roadside mowed grass green strip did have a volval sack at the base.Obviously I need to show more care when removing a specimen.I’ll send a photo of one of the smaller ones.

I thought about Volvarilla but in Volvariella there is a sac like volva at its base. Which is a primary characteristic of that species. It very well could be Volvariella speciosa . Its habitat is cultivated lawns.There appears to be salmon/ pink spore coloration on the stem. It might be that the volva was not retrieved when the mushroom was pulled from the lawn. I gave Agaricus a low vote.
Not volvariella?

I’m far from an expert in these things, but those gills, the umbo and the overall stature would have lead me to volvariella.
