Agaricus bisporus
(Button Mushroom)

Habitat

Lower elevation areas of Colorado when there is abundant moisture. Lawns and fields.

Description

A small to medium sized Agaricus with a brown cap. This mushroom stains pinkish where injured or cut. It is very reminiscent of the store bought Crimini mushroom because really it is!! It's just growing in someone's backyard rather than a dark warehouse or sitting in the produce department of your favorite grocery store. This is a possible escapee from cultivation but honestly we really do not know. It has been reported to be here in Colorado for years. Also similar bisporus types from New Mexico have been documented from ~7000ft elevation.

I've also seen a similar related mushroom from higher up in the mountains 7000 - 8000ft that is rare as well. It has very similar characteristics with more of a flocculose / scaled cap which I believe to be Agaricus subflocossus that is closely related to A. bisporus.
