North America, Europe
Cap 3-5 cm diameter, stem 4-6 cm tall * 0.3-1 cm thick

Chalciporus piperatus, also know as Peppery Bolete, is a very small bolete that is cinnamon-brown throughout, except for the chrome-yellow stem flesh; it does not stain blue on bruising. The slightly greasy cap is convex in shape, and the stem is slender; the tubes are 0.3-1 cm long. The flesh has an intensely hot and peppery flavour, making this species inedible, although it has been used as a spice.

Similar species Chalciporus piparatoides it similar but can be distinguished by the blue bruising of its cap, tubes, and pores. Chalciporus amarellus has pinker coloring and a less peppery taste.
