Found these the other day, East midlands, UK, I'm pretty sure they are Agaricus arvensis. All macroscopic features seem to match field guide.
I've done a heat test on a small piece (cooked in microwave) to check for Agaricus xanthodermus 'yellow stainer' reactions of turning yellow and smell of chemicals - there was no yellowing and it only smells nice mushroomy.
Can anyone spot anything that would indicate other ID?
