Champigñon del campo

I have been trying to identify these mushrooms and after observing different types of mushroom which exist in Uruguay, I tend to think this is a kind of "champigñon de campo" because of its shape, colour, laminates, ring....but I may be wrong, so any help is very welcome =) I know it is a kind of mushroom which we have a lot, so it may be, what calls my attention is that we found it at a nearby park ( I don´t know why it calls my attention, I just expected champignons maybe in France ;) juas!)

Thank you very much Isabella =)

Thank you Donn =)
