Pileus ovoid to convex, at length expanded, 6- 1 2 cm. broad; surface adorned with numerous 

 thin, floccose or farinose warts, variable in color, always tinged with reddish or brownish-red, 

 changing slowly to reddish when bruised, margin smooth or faintly striate; context white, 

 changing slowly to reddish when bruised, with pleasant odor and taste; lamellae free or 

 slightly adnexed, crowded, nearly plane, white, characteristically chalky- white when dry; 

 spores ovoid to ellipsoid, smooth, hyaline, 8-9 X 6-7 n ; stipe equal or slightly tapering upward, 

 usually bulbous, squamulose, whitish suffused with red, becoming reddish when bruised, stuffed, 

 6-20 cm. long, 6-12 mm. thick; annulus superior, ample, white, easily torn; volva very fragile, 

 most of the fragments appearing on the surface of the pileus, while a few remain clinging to 

 the margin of the bulb.

 or tapering upward, usually somewhat enlarged below, but scarcely bulbous, fibrillose or 

 floccose-scaly, at times conspicuously roughened, characteristically tomentose when dry,
