*8, AGARICUS PROCERUS Scop. 
Pileus at first ovate, then broadly convex or expanded, 
strongly umbonate,t spotted with broad brownish scales, 
the margin deflexed, fibrillose; lamelle remote, whitish or 
flesh colored ; stipe long, cylindrical, hollow, bulbous, squa- 
mulose, annulate with a firm movable ring. 
Height 6’-10’, breadth of pileus 3’—5’. 
Fields, pastures and roadsides. Utica. A. S. Johnson. West 
Albany. Aug.—Sept. 
An edible species of a dingy whitish color. 
9. AGARICUS ACUTESQUAMOSUS Weinm. 
Pileus convex, obtuse or very broadly subumbonate, rough 
with small erect acute scales which are more numerous on 
the disk; lamelle narrow, free, yellowish; stipe equal, 
annulate, bulbous; annulus whitish, not movable. 
Height 3’—4’, breadth of the pileus 2-3’. 
In a grapery at Buffalo. G. W. Clinton. November. 
The pileus is tawny on the disk, elsewhere whitish, with 
subconcentrically-arranged tawny scales. 
*10. AGARICUS AMERICANUS 2. Sp. 
Pileus convex, distinctly umbonate, squamose, with the 
margin obscurely striate ; lamelle free ; stipe slender, smooth, 
annulate, stuffed or hollow, gradually enlarged below into a 
long subventricose bulb-like base; annulus thin, subpersist- 
ent, fixed. 
Height 3-5’, breadth of pileus 1.5’-3’ or more. 
Grassy ground by roadsides. August. Buffalo. G. W. 
Clinton. 
The whole plant in drying becomes of a dull pinkish-red 
color. This plant was noticed in a previous report as A. 
rachodes, but upon further investigation I am satisfied it is 
a species distinct by its umbonate, not depressed pileus, 
substriate margin, fixed annulus, and peculiar elongated 
bulbous base. 
* Species marked with the asterisk have been before reported, but are repeated for 
the sake of the description. 
+ Having an abrupt obtuse elevation or boss in the center.
