subarcuate or horizontal, adnate or subdecurrent, whitish; stem firm, 
hollow, generally compressed, slightly pruinose ; spores elliptical, 
.0002 in. to .00025 in. long, .00016 in. to .00018 in. broad ; flesh white 
when dry, odor slight, farinaceous. Plant gregarious, 1 in. to 1.5 in. 
high, pileus 6 lines to 16 lines broad, stem 1 line to 2 lines thick. 
Grassy places. Albany. July. The moist pileusis sometimes obscurely 
zonate. The odor is not always perceptible unless the pileus is moist 
or broken. The stem is sometimes compressed at the top only, some- 
times at the base only, and rarely it is wholly terete. ‘The species be- 
longs to the section Orbiformes. 
Agaricus (Clitocybe) vilescens, 7. sp. Pileus convex, then plane or 
depressed, often irregular, glabrous, slightly pruinose on the involute 
margin, brown or grayish-brown, becoming paler with age, often con- 
centrically rivulose ; lamelle close, adnate or decurrent, cinereous, 
sometimes tinged with dingy yellow; stem short, solid, sometimes com- 
pressed, grayish-brown, with a whitish tomentum at the base; spores 
subglobose or broadly elliptical, .0002 in. to .00025 in. long; flesh 
whitish-gray, odor slight. Plant gregarious, i in. to 2 in. high, pileus 
lin. to 1.5 in. broad, stem 1 line to 2 linesthick. Grassy pastures.

Agaricus trullisatus, Z//is. Sandy soil. Long Island. Sept. This 
resembles the larger forms of A. /accatus, but it has a stouter habit, 
the pileus is more squamulose, the stem is bulbous or thickened at the 
base, the mycelium is violet-colored and the spores are oblong. 
Agaricus confluens, Pers. Woods. Verona and Jamesville. Aug. 
Agaricus iris, Berk. Decaying trunks of trees. Jamesville. Aug. 
Our specimens have the edge of the lamelle minutely floccose and the 
base of the stem covered with a blue mycelium. ‘The species seems 
too near A. marginellus. 
Agaricus bombycinus, Scheff. Trunks of maple trees. Buffalo. 
Clinton. Kasoag and Catskill mountains. July and Aug. 
Agaricus (Eutoloma) scabrinellus, 7. sp. Pileus thin, convex or 
nearly plane, papillate, minutely scabrous, dark-brown, the thin mar- 
gin extending slightly beyond the lamelle ; lamella broad, ventricose, 
rounded behind and slightly attached, floccose on the edge, dingy- 
white, then flesh-colored ; stem equal, fibrillose, slightly pruinose at 
the apex, paler than the pileus; spores irregular, uninucleate, .0003 in. 
to .0004 in. long, .0002 in. to .0003 in. broad. Plant about 1 in. high, 
pileus 6 lines to 1@ lines broad, stem 1 line thick. Shaded, gravelly soil 
by roadsides. Wading River. Sept. The plants are very regular in 
shape, the pileus usually has a small, papilla-like umbo and is some- 
what shining. Its roughness is scarcely visible to the naked eye. 
Agaricus curvipes, /r. Dead trunks of young trees. Verona. 
‘Aug. Our specimens have the lamelle flocose-crenate on the edge. 
Cortinarius multiformis, /’7. Woods. ° Jamesville. Aug. The 
specimens were collected in dry weather and the pileus was not per- 
ceptibly viscid except in very young plants. The bulbous base of the 
stem is not always distinctly marginate. 
Cortinarius tophaceus, /r. Woods. Jamesville. Aug. The spores 
in this species are subglobose, rough, uninucleate, .00025 in. to. 0003 
in. long, 00025 in. broad. ;
