Common mushroom (Agaricus bisporus)

Common Mushrooms (Agaricus bisporus) originate in Europe and are the most cultivated fungus in the world. They have two color states while immature—white and brown—both of which have various names. White ones are served as cooked or raw while brown ones are normally served as cooked. Their umami substance is glutamate. There is little guanylate in fresh fungi.
