Elias Magnus Fries and Christopher Theodor Hök first described this species as "Boletus torosus" in 1835, a name by which it came to be known for many years. Modern molecular phylogenetics shows that it is only distantly related to "Boletus edulis"—the type species of "Boletus"—and it was duly placed in the new genus "Imperator" in 2015.
