Observation 200402: Agaricus L.
When: 2015-03-11
No herbarium specimen

Notes: I’m new to identifying mushrooms, and don’t usually have mushrooms growing in my backyard. However, over the winter, I took a failed Crimini mushroom kit (too hot over summer for it to work) out to my backyard and set it under a Brazilian Pepper tree to see if it might revive with winter rains. Nothing happened in the box, but suddenly I have these mushrooms fruiting about 10 feet away from the box. They look like Agaricus Bisporus pushing up from under the mulch, but I need to be sure before I poison myself. A more experienced myco-friend couldn’t identify them and suggested I post here.

I’ve taken photos during several stages to identify as many traits as possible. What do you think they are? And more importantly, are they poisonous?
