Chalciporus

Chalciporus is a genus of fungi in the family Boletaceae (suborder Boletineae). There are approximately 25 species in the genus.

French mycologist Frédéric Bataille erected the genus in 1908, though it did not gain general acceptance for several decades and was often classified as a section (Piperati) of the genus Suillus or related to the genus Pulveroboletus. The type species is Chalciporus piperatus. Rolf Singer resurrected the genus in 1973, separating the species from the genus Suillus on the basis of distinct pigments. The name is derived from the Ancient Greek khalkos "copper", and translates as "copper pores".
