A truffle is the fruiting body of a subterranean ascomycete fungus, predominantly one of many species in the genus Tuber. In addition to Tuber, over a hundred other genera of mushrooms are classified as truffles, including Geopora, Peziza, Choiromyces, and Leucangium.
These genera belong to the class Pezizomycetes and the order Pezizales. Several truffle-like basidiomycetes are banned from Pezizales including Rhizopogon and Glomus.
Truffle are ectomycorrhizal fungi, so they are often found in close association with tree roots. Spore distribution is accomplished through fungivores, creatures that eat fungi. These fungi include significant ecological roles in nutrient cycling and drought patience.
Truffles belong to the genus Tuber, order Pezizales (phylum Ascomycota, kingdom Fungi).
Truffles are fungi that grow underground in forests. They are shaped like small, asymmetrical balls and can be found by burrowing, especially near tree roots. They have a distinctive earthy odor and taste.
