A bolete is a type of mushroom, or fungal fruiting body. It can be identified thanks to a unique mushroom cap. The cap is clearly different from the stem. On the underside of the cap there is usually a spongy surface with pores, instead of the gills typical of mushrooms. However, there are some boletes that are gilled, such as species of Chroogomphus, Gomphidius, Paxillus, Phylloporus and Hygrophoropsis aurantiaca. "Bolete" is the English common name for fungus species whose mushroom caps have this appearance.
