Typical mushrooms are the fruit bodies of members of the order Agaricales, whose type genus is "Agaricus" and type species is the field mushroom, "Agaricus campestris". However, in modern molecularly defined classifications, not all members of the order Agaricales produce mushroom fruit bodies, and many other gilled fungi, collectively called mushrooms, occur in other orders of the class Agaricomycetes. For example, chanterelles are in the Cantharellales, false chanterelles such as "Gomphus" are in the Gomphales, milk-cap mushrooms ("Lactarius", "Lactifluus") and russulas ("Russula"), as well as "Lentinellus", are in the Russulales, while the tough, leathery genera "Lentinus" and "Panus" are among the Polyporales, but "Neolentinus" is in the Gloeophyllales, and the little pin-mushroom genus, "Rickenella", along with similar genera, are in the Hymenochaetales.
