Fruiting body in plain English
It is the part most people picture when they hear “mushroom”: the cap, stem, shelf, cluster, or other visible structure. The organism may also include extensive mycelium inside wood, soil, grain, or another substrate, so the fruiting body is important but is not the entire fungus.
