It i'* n*^n MUSHROOM color, and as the plant ages become purple-brown or blackish in color, due to the immense number of spores borne on the surface. One can gain a good idea of the number of spores borne on a single plant by cutting a cap from a Mushroom, just at maturity, and placing it, gills downward, on a piece of white paper for a few hours. The spores fall from the gills and pile up in ridges, giving an exact print of the spaces between the gills. The parts of the plants enumerated above are easily seen. Other important structural characters are seen with the aid of the mi- croscope. A thin section across the gills when seen with the microscope shows the structure as seen in Fig. 1442.

This palisade layer of the basidia forms the fruit- ing surface, or hymenium. At the end of each basidium are either 2 or 4 slender, pointed iirocesses. the slerig- tmtfii ( sing, sterigma). These bear each a sin- gle spore, the basidiospore. The usual num- ber of sterigmata on the basidium in the Agaricini is 4; but in Agariciis i-ampcstris the number seems to vary from 2 to 4. In plant
