Boletus rex-veris, commonly known as the spring king bolete, is a basidiomycete fungus of the genus Boletus found in western North America. The large, edible fruiting bodies known as mushrooms appear under pine trees, generally in May to June. It has a pinkish to brownish cap and its stem is often large and swollen, and the overall colour may have an orange-red tinge. As with other boletes, the size of the fruiting body is variable. Boletus rex-veris is edible, and may be preserved and cooked.
