and peeling up around the margin or breaking away in scales, 

 sometimes altogether persistent. Stipe arising from a slightly 

 thickened or bulbous base, fistulous, fibrous-stuffed, white, smooth 

 and glabrous ; the annulus firm, membranaceous. Lamellae broad, 

 close, white, tapering inward and remote from the stipe ; spores 

 elHptic-oblong, 14-16x9-11 mic. 



Growing in pastures and fields. New England, Frost; N. 

 Carolina, Curtis; Alabama, Atkinson; Pacific Coast Cat. Pileus 

 5-7 cm. in diameter, the stipe 6-8 cm. long and 6-10 mm. thick. 

 Withering and Persoon considered this species to be a small form 

 of Lepiota procera ; the size of the spores lends countenance to 

 this opinion.

 Peck, 29 N. Y. Rep. 1876; Agaricus naucinus Peck, 23 N. Y. 

 Ref. 1870; Morgan, Myc. Flora M. V. 



Pileus fieshy, subovoid and obtuse, then convex, expanded 

 and explanate, subumbonate ; the flesh thick, white ; the dermis a 

 thin membrane, white or smoky white, its surface commonly 

 smooth and glabrous, but sometimes the cuticle breaks up into 

 very minute fibrillose scales. Stipe tapering upward from a cla- 

 vate base, fistulous, fibrous-stuffed, white, smooth and glabrous 

 or becoming slightly fibrillose toward the base ; the annulus thin, 

 membranaceous, white, persistent. Lamellae broad, close, free, 

 white, after maturity slowly changing in color to a dull livid ; 

 spores elliptic-ovoid, 8-9 x 5-6 mic. uniguttulate. 



Gregarious ; growing in grassy grounds, pastures, roadsides, 

 etc. Eastern U. S. westward to Kansas. Pileus 4-8 cm. in diam- 

 eter; the stipe 8-12 cm. in height, 6-12 mm. thick at the apex, 1-2 

 cm. thick at the base. European writers evidently confuse two 

 species. Agaricus naucinus of Fries, and Berkeley, is A. sphae- 

 rosporus Krombliz. Lepiota naucina Bresadola, Fung. Mang. 

 is A. naucinoides Peck. Agaricus naucinus with spherical spores 

 occurs also in Australia; See Cooke's Handbook of Australian 

 Fungi. 



82. LEPIOTA SOLIDIPES Peck, 52 N. Y. Rep. 1898. 



Pileus fleshy, subhemispheric then convex and nearly plane ; 

 the flesh thick white ; the dermis a continuous membrane, the 

 surface smooth and glabrous, white sometimes with a slight pink- 

 ish tint. Stipe nearly equal or somewhat bulbous, solid, whitish, 

 silky-fibrillose ; the annulus thin, subevanescent. Lamellae close, 

 free, white ; spores subglobose, 4-5 mic. in diameter. 



Growing in damp or swampy ground. New York, Peck. 

 Pileus 5-10 cm. in diameter, the stipe 5-10 cm. long and 8-I2' 

 mm. thick. This species is distinguished from Lepiota naucina 

 by its solid stipe and perhaps also by its smaller spores.
