Classification

Typical mushrooms are the fruit bodies of members of the orderAgaricales, whosetype genusisAgaricusand type species is the field mushroom,Agaricus campestris. However, in modernmolecularlydefinedclassifications, 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 classAgaricomycetes. For example,chanterellesare in theCantharellales, false chanterelles such asGomphusare in theGomphales, milk mushrooms (Lactarius) and russulas (Russula), as well asLentinellus, are in theRussulales, while the tough, leathery generaLentinusandPanusare among thePolyporales, butNeolentinusis in theGloeophyllales, and the little pinmushroom genus,Rickenella, along with similar genera, are in theHymenochaetales.
