context_page_description: Chalciporus piperatus, commonly known as the peppery bolete, is a small pored mushroom of the family Boletaceae found in mixed woodland in Europe and North America. It has been recorded under introduced trees in Brazil, and has become naturalised in Tasmania and spread under native Nothofagus cunninghamii trees. A small bolete, the fruit body has a 1.6–9 cm orange-fawn cap with cinnamon to brown pores underneath, and a 4–9.5 cm high by 0.6–1.2 cm thick stipe. The rare variety hypochryseus, found only in Europe, has yellow pores and tubes.
  Described by Pierre Bulliard in 1790 as Boletus piperatus, it is only distantly related to other members of the genus Boletus and was reclassified as Chalciporus piperatus by Frédéric Bataille in 1908. The genus Chalciporus was an early branching lineage in the Boletaceae and appears to be related to boletes with parasitic properties. Previously thought to be ectomycorrhizal, C. piperatus is now suspected of being parasitic on Amanita muscaria. The flesh of C. piperatus has a very peppery taste, and can be used as a condiment or flavouring.
context_section_description: French mycologist Pierre Bulliard described the species as Boletus piperatus in 1790. In its taxonomic history, it has been transferred to the genera Leccinum (Samuel Frederick Gray, 1821), Viscipellis (Lucien Quélet, 1886), Ixocomus (Quélet, 1888), Suillus (Otto Kuntze, 1898), and Ceriomyces (William Alphonso Murrill, 1909). It was reclassified and given its current binomial name in 1908 by Frédéric Bataille when he made it the type species of the newly circumscribed genus Chalciporus.  The species name piperatus means "peppery" in Latin. It is commonly known as the "peppery bolete".
  Chalciporus piperatus is a member of the genus Chalciporus, with which the genus Buchwaldoboletus form a group of fungi that is an early offshoot in the Boletaceae. Many members of the group appear to be parasitic.
  Two varieties have been described. Chalciporus piperatus var. hypochryseus was originally described as Boletus hypochryseus by Czech mycologist Josef Šutara in 1993, and was moved to Chalciporus a year later by Regis Courtecuisse. Wolfgang Klofac and Irmgard Krisai-Greilhuber reclassified it as a variety of C. piperatus in 2006, although some sources continue to regard it as a distinct species. Variety amarellus, first published by Quélet as Boletus amarellus in 1883 and later transferred to Chalciporus by Bataille in 1908, was described as a variety of C. piperatus in 1974 by Albert Pilát and Aurel Dermek. Authorities disagree as to whether or not it has independent taxonomic significance.
