Gyroporus purpurinus

Gyroporus purpurinus is a species of bolete fungus in the family Gyroporaceae. Found in eastern North America, it was first described in 1936 by Wally Snell as a form of Boletus castaneus. Snell and Rolf Singer transferred it to Gyroporus a decade later. Neither of these publications were valid according to the rules of botanical nomenclature, which at the time mandated a description in Latin. In 2013, Roy Halling and Naveed Davoodian published the name validly.

The species is edible.
