I found these growing in a grassy area after a rainstorm in Northern California. They were growing in bunches of about 5-6 each, and have a color that ranges from off white to dark tan, with a. Yellow cast. The mature stems are about 3 inches, with caps of about 1 inch. They smell like white button mushrooms and bruise a brownish color.
i am assuming these are either poisonous or not very tasty even if they aren't, so I have no intentions of eating one. I just want to identify them for fun and the educational value.
