Boletus rex-veris

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.

For many years, Boletus rex-veris was considered a subspecies or form of the porcini mushroom B. edulis. In 2008, a taxonomic revision of western North American populations of this species was published, formally establishing it as a distinct species, Boletus rex-veris. Phylogenetic analysis has shown B. rex-veris as a member of a clade, or closely related group, with B. fibrillosus, B. pinophilus, B. subcaerulescens, Gastroboletus subalpinus, and B. regineus.
