86 TWENTY-THIRD REPORT ON THE STATE CABINET. 
On rotten logs and stumps in woods and open places. 
May-October. Very common. 
656. Agaricus FrsuLta Bw. 
Pileus thin, convex, umbilicate, smooth, yellow or pale 
orange, striatulate ; lamelle narrow, arcuate, long decurrent, 
whitish ; stipe elongated, slender, smooth, hollow, concolorous. 
Height 1’-2’, breadth of pileus 1’-3”. 
On mossy ground in fields and groves. June—October. 
Common. 
The pileus becomes brighter colored in drying. 
Subgenus — Pleurotus. 
Stem eccentric, lateral or wanting. Mostly growing on 
wood.— Berk. Out. 
In this subgenus the pileus is either destitute of a stem or has 
it attached to the margin or to some point outside of the center. 
The texture is more firm, the plant of slower growth and longer 
duration than in any of the preceding subgenera.

58. AGARICUS SULFUREOIDES 7. sp. 
Pileus rather thin, fleshy, convex, umbonate, subsquamu- 
lose or smooth, sulphur-yellow ; lamelle moderately close, 
rather broad, rounded or slightly emarginate at the inner 
extremity, easily separating from the stipe, pale yellow ; stipe 
firm, equal, slightly fibrillose, stuffed or hollow, generally 
curved and eccentric, rarely central, a little mealy-tomentose 
at the top. 
Height 1’-1.5’, breadth of pileus 1’-2’, stipe 2’-3” thick. 
On old logs in woods. Catskill Mountains. October. 
The pileus becomes paler in drying. The minute scales are 
brown, but often wanting. It resembles A. sulfureus, but 
from its firm texture and eccentric stipe it must be placed 
with the Pleuroti. 
59. AGARICUS SEROTINOIDES 72. sp. 
Pileus fleshy, thick, firm, convex above, minutely punctate- 
tomentose, slightly viscid when young or moist, the margin 
usually incurved ; lamellz close, determinately ceasing, some 
of them forked, white or yellowish ; stipe lateral, short, thick, 
scarcely distinct when viewed from above, yellow and tomen- 
tose beneath. fe,
