74 Twenty-third Report on the State Cabinet. 



17. Agaeicus variegatus Scop. 



Pileus fleshy, convex, at length expanded or slightly de- 

 pressed, variegated vrith a red squamulose tomentum ; 

 lamellae narrow, close, pale yellow or whitish ; stipe equal, 

 stufied, tomentose like the pileus. 



Height 2', breadth of pileus 2', diameter of stipe 3"- 6". 



About the roots of old stumps. Albany and Sandlake. 

 June. 



The flesh of the pileus is whitish, inclining to yellow. The 

 color of the tomentum varies in intensity. It is usually 

 paler, as well as less dense, on the stem than on the pileus. 



18. Agaricus vaccinus Pers. 



Pileus fleshy, rather thin, except the disk, at first ovate- 

 convex, then subcampanulate or expanded, generally 

 broadly umbonate, dull reddish-brown with innate blackish 

 fibres or scales, generally rough squamose from the break- 

 ing up of the cuticle ; lamellaj whitish, at length becoming 

 spotted and margined with dull rufous, close or subdistant, 

 slightly or deejDly emarginate ; stipe concolorous with the 

 pileus, whitish and pruinose at the top, fibrous-scaly, equal 

 or subventricose, stuffed or hollow. 



Height 2-3', breadth of pileus 2'- 3', diameter of stipe 

 4"-6". 



Ground under balsam trees in pastures. Catskill Moun- 

 tains. October. 



A very variable species, not agreeing rigidly with the 

 description of A. Tiaccinus^ but I am unwilling to found a 

 new species on the slight differences exhibited by so variable 

 a plant. Two principal forms are noticeable ; one, with the 

 pileus smooth, expanded, not umbonate, the margin smooth, 

 marked at little intervals with slight, short, polished eleva- 

 tions, and the lamellaB close ; the other, with tlie pileus con- 

 vex-cami)anulate broadly umbonate, rimose-squamose, the 

 margin when young slightly tomentose, and the lamellae 

 subdistant, often wavy and marked with little transverse 

 lines. The latter form is the more common one. The color 

 inclines to cinnamon-brown. 



19. Agaricus terkeus SchcFff. 



Pileus fleshy on the disk, elsewhere rather thin, convex, 

 then expanded, with a short broad iimbo, densely squamu- 

 lose, dark or livid -brown, the floccose scales blackish, often 

 bluish tinged ; lamellae whitish, subdistant, thick, ventricose, 

 deeply emarginate or subrounded at the inner extremity, 

 with a slight decurrent tooth ; stipe equal or slightly tapering
