Crimini mushrooms are a coffee-colored variety of the world's most commonly eaten mushroom, commonly called the "button" mushroom. The names "white button," "crimini" and "portobello" all refer to this same scientific category of mushroom.

Like most mushrooms, crimini mushrooms can provide us with unique immune system support. But contrary to public belief, these common button-type mushrooms have recently been shown to surpass some of their more exotic mushroom counterparts (like shiitake or maitake mushrooms) in terms of immune system benefits.
