The subterranean mycelium is cord-like and from it the MUSHROOMS AND TOADSTOOLS 247 fruit body arises which has a peridium of two or three layers. Theouter ])eri(lium is leathery and tough, while the inner ])eri(lium is gelat-inous at maturity. The outer peridium remains at the l)ase, as acup called the volva. The sporophore, i)ileus, or cap, is raised up on theend of a stalk, or stipe, which is usually spongy in character. Thesporophore takes a variety of forms, but in all cases, its outer surface at.

In fact, it has been proved thatthe basidiospores germinate better after passage through the alimentary 248 MYCOLOGY canals of flies. The gleba is the fruiting portion of the phalloid and itsbulk appears considerable in the early egg-shaped stage of the fruitbody. As the carrion fungus matures, it forms proportionately less ofthe fruit body, for it is converted into the greenish, mucilaginous masswhich is removed by the flies.
