Certified Organic White Button Mushrooms from Mother Earth Farm in Landenberg, Pennsylvania.

Both the cap and the stem of a white button mushroom are edible.  Fun Fact: White Buttons are harvested in the youngest stage of development.  If left to mature further, the brown crimini mushroom is what you'd get, and eventually the full grown Portabella mushroom is the adult stage.

Storage Tips: Store in a paper bag in the refrigerator, or place on a tray and cover with a wet paper towel. They'll last 2-5 days or more.
