It’s generally a good idea to also include photos of - spore print - cuts on the mushroom made a while ago and immediately - habitat or discussion of habitat and nearby flora

Not 100%, but it looks like meadow mushroom family. I have horse mushrooms in my yard that look very similar

It is likely a member of the Agaricus genus, which is part of the Agaricaceae family.

Could you provide a photo with the specimen divided into left and right halves? (split evenly).

Not enough to truly identify, but it looks a lot like agaricus cupreobrunneus
