Boletus regineus

Boletus regineus, commonly known as the queen bolete, is an edible and highly regarded fungus of the genus "Boletus" that inhabits southwestern North America. It was considered a variant of the similarly edible "B. edulis" for many years until declared a unique species in 2008. Phylogenetic analysis has shown "B. regineus" as a member of a clade, or closely related group, with "B. subcaerulescens", "Gastroboletus subalpinus", "B. pinophilus", "B. fibrillosus", and "B. rex-veris".
