REPORT OF THE BOTANIST. 53 
Agaricus (TricHotomaA) Hesetoma Peck. 
Pileus broadly conical or subcampanulate, obtuse, thin, hygro- 
phanous, striatulate and brown, with a darker disk when moist, 
grayish when dry; lamelle broad, rounded behind and deeply 
emarginate, yellowish; stem equal, hollow, smooth, pallid; spores 
.00028 x .00016 in. 
Plant 1’ high, pileus 6" broad, stem scarcely 1" thick. 
Ground in woods. Worcester. July. 
This plant so closely resembles some species of the subgenus 
Hebeloma in general appearance, that, in the absence of the spores, 
it might easily be mistaken for a species of that subgenus. 
Agaricus (Ciirocysr) connexus Peck. 
Pileus thin, convex or expanded, subumbonate, clothed with a 
minute appressed silkiness, white, the margin sometimes faintly 
tinged with blue; lamellz crowded, narrow, white inclining to 
yellowish ; stem equal or tapering downwards, solid, whitish. 
Plant 2'-3’ high, pileus 2’-3' broad, stem 2” thick. 
Ground in woods. Croghan. September. 
The lamellee sometimes terminate rather abruptly and are not 
strongly decurrent, hence it might easily be mistaken for a Tricho- 
loma. The margin of the pileus is sometimes marked with slight 
ridges as in Ag. laterarius. The odor is weak but aromatic and 
agreeable. 
Agaricus (CiirocysBe) aLtBisstmus Peck. 
Pileus convex or expanded; dry, smooth, soft, pure white ; 
lamelle close, short-decurrent, white, some of them forked at the 
base ; stem equal, smooth, solid, white. 
Plant growing in rings, 2-3' high, pileus 2’-3' broad, stem 
2"-3" thick. 
Ground in woods. Croghan. September. 
The pure white color and soft texture is retained in the dried 
specimens. 
Agaricus (Ciirocysr) MAcuLosus Peck. 
Pileus convex, centrally depressed, smooth, marked with nume- 
rous watery spots when moist, yellowish-white, with slight short 
radiating ridges on the margin; lamellz crowded, narrow, long- 
decurrent, pallid or yellowish, some of them forked; stem slightly 
thickened at the base, smooth, stuffed or hollow, colored like the 
pileus. 
Plant 2'-3' high, pileus 1.5’-2' broad, stem 2"-3" thick.
