78 TWENTY-THIRD REPORT ON THE STATE CABINET. 
June—October. 
An extremely variable and abundant species occurring 
almost everywhere throughout the season. 
30. AGARICUS BRUMALIS /7. 
Pileus thin, at first convex, then expanded or depressed, 
umbilicate, smooth, hygrophanous; lamelle narrow, close, 
slightly decurrent ; stipe slender, smooth, equal, hollow. 
Height 1-2’, breadth of the pileus 8’-18", stipe 1’- 2” thick. 
Pine woods. West Albany. October. 
The plant is watery gray when moist, dull white when dry. 
I do not find it deeply funnel form. 
31. AGARICUS DITOPUS FY. 
Pileus thin, submembranaceous, convex, rarely with a small 
umbo, smooth, hygrophanous, brown when young and moist, 
grayish-white when dry ; lamelle grayish, close, thin, attached, 
not decurrent; stipe slender, equal, smooth, hollow. 
Height 1-2’, breadth of pileus 6"-18", stipe 1’- 2” thick 
Pine woods. West Albany. October. 
The plant has the odor and taste of new meal. I have seen 
no specimens with the pileus depressed. 
32. AGARICUS METACHROUS /7. 
Separated from the preceding by its thicker, depressed pileus, 
its thicker, less close lamelle, and the absence of odor. 
Pine woods. West Albany. October. 
Subgenus — Collybia. 
Stem cartilaginous externally. Margin of pileus at first invo- 
lute. Gills not decurrent.—Berk. Out. 
The pileus is generally convex or expanded, not obconic or 
depressed, as in the preceding subgenus. The lamelle reach 
the stem, but are not decurrent, though sometimes emarginate 
as in 7richoloma. The stipe is firm and cartilaginous, without 
any annulus.
