Is this a field mushroom I found in the grass

[Mikey242]

Hello all

Found this mushroom in my back garden and was wondering what it is? I think it's a field mushroom but just wanted to check what you think (not planning on eating it either way).





Just noticed I didn't add a scale to the photos, hope that's ok.

Thanks

The first photo looks so deadly white I thought it was a Destroying Angel at first. The second photo with the chocolate gills suggest Agaricus though. Can't see a ring. Is there a ring?

I think it came out so bright in the first photo because I used flash.

There is a ring, very thin and membranous, was loosely attached to cap on inside when I picked it.
