Butyriboletus fuscoroseus

Butyriboletus fuscoroseus is a pored mushroom in the family Boletaceae. It was formerly considered a species of "Boletus", but in 2014 was transferred to the newly created genus "Butyriboletus". "Boletus pseudoregius", a European taxon originally described as a subspecies of "Boletus appendiculatus" in 1927, is a synonym. "B. fuscoroseus" is considered critically endangered in the Czech Republic.
