About Chalciporus piperatus in brief

Summary Chalciporus piperatusChalciporus 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. The flesh of C.  piperatus has a very peppery taste, and can be used as a condiment or flavouring. The rare variety hypochryseus, found only in Europe, has yellow pores and tubes. The spores are smooth, narrowly fusiform, and measure 7–12 by 3–5µm. The spore print is brown to cinnamon to cinnamon brown, sometimes with reddish, maturing to purplish brown. The basidia are hyaline, four-spored, narrowly club-shaped, with many internal oil-shaped internal oil droplets and many internal club-like club-sized spines.

It is one of the smaller boletes, with an orange-fawn 1. 6–9 cm cap that is initially convex before flattening out in age. The colour of the pore surface ranges from cinnamon to dark reddish brown in maturity. The cap surface can be furrowed; shiny when dry, it can be a little sticky when wet. When bruised, the p pores are angular, measuring about 0. 5–2 mm wide, while the tubes are 3–10 mm deep, and have no odour. In its taxonomic history, it has been transferred to the genera Leccinum, Viscipellis, Ixocomus, Suillus, and Ceriomyces.
