Caloboletus frustosus

Caloboletus frustosus is a bolete fungus native to North America. Until 2014, it was known as Boletus frustosus. Recent changes^[2][3] in the phylogenetic framework of the family Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus.^[4] It was first described scientifically in 1941 by mycologists Wally Snell and Esther Dick.^[5]
