0 TWENTY-FOURTH REPORT ON THE STATE MUSEUM. 
when dry; lamelle subdistant, free, grayish or pallid becoming 
dingy flesh-colored; stem lateral, short, solid, curved, fibrillose 
toward the base, springing from an abundant, white, radiating 
mycelium which sometimes creeps over the matrix to a considerable 
distance; spores subglobose, irregular, flesh-colored, about 39/59’ 
long. 
Pileus 5-10" broad, stem scarcely more than 1" long. Very 
rotten, mossy logs in woods. Greig. . September. 
The short stem is sometimes compressed in the middle so that 
it appears to be enlarged both above and below. This species 
belongs to the second division of the subgenus Crepidotus as 
characterized by Fries in the Epicrisis, and to the subgenus Claw- 
dopus proposed by W. G. Smith, except that the lamellee are free, 
neither sinuate nor decurrent. It is manifestly related to A. 
byssisedus. 
Agaricus (Prnosacr) EXIMIUS 2. sp. 
Pileus fleshy, thin, convex or broadly campanulate, at length 
expanded and subumbonate, smooth, dark sooty brown; lamellee 
close, broad, ventricose, rounded behind, free, dull red or brownish 
pink, then brown; stem slender, hollow, a little thicker at the base, 
dull red; spores elliptical, zy'yq long. 
Plant 1’ high, pileus 3’—6" broad, stem .5" thick. Old stumps in 
woods. Greig. September. Rare. 
I am not aware that a representative of this subgenus has before 
been found in this country, and none is yet known to belong to 
the flora of England. 
Agaricus (Pstmocyse) Lritcoxa n. sp. 
Pileus thin, convex, then expanded, smooth, hygrophanous, 
dark watery brown and striatulate on the margin when moist, pale 
ochraceous brown and corrugate-wrinkled when dry ; lamellee close, 
rounded behind, attached, cinnamon-brown, becoming darker ; 
stem slender, equal, brittle, silky, hollow above with a distinct 
separable pith below, whitish ; spores elliptical-cymbiform, 39’ 
long. 
Plant subecespitose, 2’ high, pileus 6’-12" broad, stem scarcely 
1" thick. Damp muck soil in woods. Greig. September. (Plate 
2, figs. 9-13.) 
Related to A. cernuus, but more slender and fragile, with a- 
- different habitat, larger spores, ete. 
Agaricus (PsATHYRELLA) ODORATUS %. Sp. 
Pileus thin, fragile, ovate-convex, at length expanded, smooth, 
hygrophanous, dark reddish brown or chestnut colored and stria-
