The earthy flavor of the mushrooms make them suitable for soups, sauces and stews. Cooked portions will often turn blue, then gray, then return to their original yellow color. "Butyriboletus appendiculatus" is found in Europe and North America. Fruit bodies grow singly, scattered, or in groups under hardwood trees. In North America, it is more common in the Pacific Northwest region, where it often associates with live oak and tanoak.
