, and other fruiting body morphologies. Similar pore surfaces exist in the polyporales and other orders, but these species usually lack the overall physical structure of boletes, have much firmer (often woody) flesh, or are otherwise differentiated.

Generally the term refers to members of the genus Boletus
Boletus

Boletus is a genus of mushroom, comprising List of bolete species. The genus Boletus was originally broadly defined and described by Elias Magnus Fries in 1821, essentially containing all fungi with pores....
, but as superficially similar fungi have been placed in other genera many of them have retained the common name. These include:

  • Birch bolete - Leccinum scabrum
  • Bitter bolete - Tylopilus felleus
    Tylopilus felleus

    Tylopilus felleus, formerly Boletus felleus, is a fungus of the Boletaceae, found in Northern Europe and North America. It derives its specific name from the Latin fel meaning "gallbladder" referring to its bitter taste, like gallbladder....
  • Manzanita bolete - Leccinum manzanitae
  • Rhubarb bolete - Boletellus obscureococcineus
