The descriptions of the various species have been taken pri- 

 marily from those by Copeland.* 



AGARICUS ARGYROSTECTUS Copel. 



Agmricus argyrostectus is recognized by a pileus 3.5 centi- 

 meters wide passing from conical to convex-plane and by 

 being shiny white, always naked, subfleshy, with unchanging 

 gray flesh. It is without odor and has an agreeable taste. 

 The gills are 3 millimeters deep, free, obtuse at both ends, 

 gray at first, but later turning dark. The spores are 5.5 to 

 6 by 4 to 4.5 microns and without guttules. The stipe is 3 to 4 

 centimeters high, 4 to 3 millimeters thick, firmly attached to 

 the pileus, terete, scarcely enlarged downward, and solid or 

 nearly so. The annulus is membranous, pendent, and early 

 breaking up and disappearing. The fungus is not common, 

 growing in »sunny pastures, and described from Davao. 



AGARICUS BOLTON I Copel. 



Agaricus boltoni has a pileus 10 to 15 centimeters wide, 

 passing from globose through cylindrical and conical to more 

 or less plane. It is clothed with brown scales, which are 

 denser and larger toward the disk. The disk is fissured, 

 plane, or subumbonate. It is fleshly, white, well flavored, and 

 about odorless. The gills are numerous, crowded, free, 6 

 millimeters deep, white when young and ultimately dark brown. 

 The spores have short basal appendages and are 8 to 9 by 5 to 6 

 microns. The stipe is 18 to 16 centimeters high, stout with glo- 

 bose base, and becoming hollow with age. The annulus is fixed, 

 ample, persistent, declined, and subentire. The species is com- 

 mon in sunny pastures in Davao. (Fig. 17). 



AGARICUS LUZONENSIS Graff. 



The fungi of this species f are solitary and have a slight 

 odor. The pileus is fleshy, convex to expanded, clothed complete- 

 ly, except for the solid red-brown center, with delicate red 

 brown fibrils, the outer two-thirds showing the white flesh of the 

 cap between. It is soft, smooth, with a thin margin, 7 to 9 

 centimeters in diameter. The flesh is white, 5 millimeters thick. 

 The margin usually has remnants of the membranaceous veil 

 attached. The stipe varies in diameter from 9 millimeters just
