Agaricus (GALERA) CALLISTUS Peck. 
Pileus thin, expanded, subumbonate, smooth, viscid, striatulate 
on the margin, olivaceous or ochraceous, the umbo bright chestnut 
color; lamellze thin, close, ventricose, attached to but easily sepa- 
rating from the stem, yellowish, becoming bright ferruginous; 
stem equal, hollow, pruinose, yellow; spores .00035 x .0002 in. 
Plant 11.5’ high, pileus 6-10" broad, stem .5” thick. 
Exsiccated water holes in swampy woods. Croghan. Sep- 
tember. 
This is one of the prettiest Agarics known to me. In the dried 
specimens the lamelle are white on the edge and the pileus has 
assumed a dull metallic green color. 
Agaricus (GALERA) coprinorpEs Peck. 
Pileus membranaceous, soon expanded, often split on the mar- 
gin, plicate-sulcate to the small even disk, yellowish, inclining to 
ochre; lamellz close, slightly rounded behind, concolorous ; stem 
equal, hollow, minutely hairy-pruinose, white; spores .00028 x 
.0002 in. 
Plant 1’ high, pileus 6" broad, stem .5" thick. 
Grassy ground. Sterling. August. 
The structure of the pileus is like that of some of the smaller 
Coprini. 
Agaricus sitvaticus Scheff. 
Buffalo. Clinton. I have seen dried specimens only, but they 
appear to belong to this species. 
Agcaricus (Psauziota) piminutivus Peck. 
Pileus expanded or centrally depressed, sometimes with a slight

appressed silky scales ; lamellee close, thin, free, ventricose, brown- 
ish-pink, becoming black ; stem equal or slightly tapering upward, 
stuffed with a whitish pith or hollow, smooth, pallid; annulus thin, 
persistent, white ; spores .0002 x .00015 in. 
Plant 1.5'-2' high, pileus 1’'-1.5' broad, stem 1°—2" thick. 
Ground in woods. Croghan. September. 
Sometimes the whole pileus is colored reddish-brown. The flesh 
is quite brittle.
