subarcuate or horizontal, adnate or subdecurrent, whitish ; stem firm, 

 hollow, generally compressed, slightly prninose ; 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, pilens 6 lines to 16 lines broad, stem 1 line to 2 lines thick. 

 Grassy places. Albany. July. The moist pileus is 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, n. 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 ; lamellae 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, 1 in. to 2 in. high, pileus 

 lin. to 1.5 in. broad, stem 1 line to 2 lines thick. Grassy pastures.

Agaricus trullisatus, Ellis. Sandy soil. Long Island. Sept. This 

 resembles the larger forms of A. laccatus, 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 lamellae minutely floccoseand the 



base of the stem covered with a blue mycelium. The species seems 



too near A . marginellus. 



Agaricus bombycinus, Sclmff. Trunks of maple trees. Buffalo. 

 Clinton. Kasoag and Catskill mountains. July and Aug. 



Agaricus (Entoloma) scabrinellus, n. sp. Pileus thin, convex or 

 nearly plane, papillate, minutely scabrous, dark-brown, the thin mar- 

 gin extending slightly beyond the lamellae ; lamellae 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 10 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, Fr. Dead trunks of young trees, Verona. 

 Aug. Our specimens have the lamellae flocose-crenate on the edge. 



Cortinarius multiformis, Fr. 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, Fr. Woods. Jamesville. Aug. The spores 

 in this species are subglobose, rough, uninucleate, .00025 in. to. 0003 

 in. long, 00025 in. broad.
