Agaricus bitorquis

First good find of the 2011 season was a new one for me. My wife said there were white mushrooms in the mint patch in the backyard. Couldn't imagine what they could be, so I checked immediately. Turns out they were Agaricus bitorquis, which are usually found early before other Agaricus make an appearance. We fried them in butter, applied a light dash of salt and ate them on toast. Delicious.
