A striking eastern North American butter bolete with a pinkish-purple to dark purplish-red cap, lemon-yellow pores and a bright yellow netted stem. All parts stain dark blue when cut or bruised. It was described in 2000 and moved to Butyriboletus in 2015. Its separation from Boletus speciosus is still unresolved on ITS data.
Edibility is not documented in the sources reviewed; not recommended. It stains dark blue and tastes very sour, and it can be confused with other red- or purple-capped, blue-staining boletes whose edibility varies.
