GILL FUNGI AGARICACEAE 



The fruit-body is generally cap-shaped or mnbrella-shaped, with a central stem, 

 though in a few cases the stem is lateral or wanting. The spores are borne on 

 plates or gills which radiate from the stem to the edge of the cap. The gills are 

 on the under side, except when the cap is stemless and inverted. At first, the gills 

 are protected by a membranous or cobwebby veil, which is torn as the cap expands, 

 but often remains as a ring on the stem, or hangs as a fringe from the edge of the
