70 Twenty-third Report ox the State Cabinet, 



mealy, hollow or loosely stuffed witli cottony fibres, not an- 

 nulate, slieatlied at the base with the persistent volva. 



Height 3-6' breadth of the pileus l'-4'. 



Common in woods. August. 



The color of the pileus is various, but commonly a livid or 

 grayish -brown. I have seen the white variety, A. nivalis 

 Grev., on sterile grassy banks in Keene, Essex county. 

 Patches of the torn volva may be seen on the young pileus. 



6. Agaricus Cecilije B. & Br. 



Pileus sulcate-striate on the margin, grayish-brown, warty, 

 at first ovate and slightly viscid, then broadly convex, ex- 

 panded or even slightly depressed ; lamellae broad, white, 

 free; stipe white, slightly tapering upward, minutely squa- 

 mulose, hollow or stuff'ed with cottony fibres, not annulate ; 

 the volva soon disappearing. 



Height 4-6', breadth of pileus 2'- 3'. 



Grassy borders of a grove at Greenport. July. 



This species is closely related to the preceding one, but 

 easily separated by the warty pileus and evanescent basal 

 portion of the volva. I do not find the stem more densely 

 stufied than it is in A. xaginatus. 



7. Agaricus faeinosus Scliio. 



Pileus sulcate-striate on th«? margin, livid-brown, pulveru- 

 lent coated ; lamellae whitish, free ; stipe pallid, cylindrical, 

 becoming hollow, farinaceous, subbulbous, not annulate ; 

 volva evanescent or none. 



Height 2', breadth of tlie pileus l'-2'. 



In open woods. Greenbush. July. 



The powdery or dust-like coating of the pileus is more 

 abundant on the disk, whei'e it is collected in heaps or patches 

 capable of being rubbed off". The plant might easily be mis- 

 taken for a species of Russula. 



Subgenus — Lepiota. 

 Veil universal, concrete with the cuticle of the pileus. Hj'men- 



ophorum distinct from the stem. — Berlc. Ontl. 

 The species of this subgenus are generallj^ smaller than those 

 of the preceding, and the most of them have the pileus rough 

 with tufts or scales formed by the breaking up of the cuticle 

 with the concrete veil. This frt^quently gives them a beautiful 

 variegated appearance.
