25. Agaricus illudeis^s Schw. 



Pileus fleshy, convex or expanded, smooth, generally with 

 a small umbo ; lamellae not crowded, unequally decurrent, 

 some of them branched, narrowed toward each end, the edge, 

 in dr}^ specimens, discolored ; stem firm, solid, long, smooth, 

 tapering at the base. 



Height 5'- 8', breadth of pileus 4'- 6', stipe 6"- 8" thick. 



Generally growing on rotten wood. Common. 



The plant is of a bright saffron yellow color, and grows in 

 dense clusters or tufts, so that the pileus is often irregular or 

 excentric from its crowded mode of growth. The cuticle 

 sometimes crarcks in areas, and the color, when old, becomes 

 brownish. The large bright-colored tufts form a conspicuous 

 object, and catch the eye at a considerable distance. 



27. Agakicus Adiroxdackensis n. sp. 



Pileus thin, submembranaceous, funnel form, with the 

 margin decurved, nearly smooth, hygrophanous, white, the 

 disk often darker ; lamellae white, very narrow, scarcely 

 broader than the thickness of the flesh of the pileus, crowded, 

 long decurrent, subarcuate, some of them forked ; stipe slen- 

 der, subequal, not hollow, whitish, mycelio-thickened at the 

 base. 



Height l'-3', breadth of pileus l'-2', diameter of stipe l"-2\ 



Among leaves in woods. August. 



I have seen this pretty species in the Adirondack region 

 only. The lamellae are sometimes tinged with yellow. The 

 margin of the pileus is occasionally wavy. 



28. Agaricus Poculum n. sp. 



Closely related to the preceding, being of the same size and 

 shape, but differing in being of a grayish-brown color, liaving 

 the lamellae less crowded, twice as broad, and darker colored. 



Woods. North Elba and West Albany. August-October. 



29. Agaricus laccatus Scop. 



Pileus thin, fleshy, convex, sometimes expanded, even or 

 slightly umbilicate, smooth or minutely tomentose -scaly, hy- 

 grophanous, when moist, dull reddish-yellow or reddish-flesh- 

 colored, sometimes striatulate ; when dry, pallid or pale dull 

 ochraceous ; lamellae broad, rather thick and distant, attached, 

 not decurrent, flesh-colored ; stipe slender, firm, fibrous, stuffed, 

 equal, concolorous. 



Height 1'- 6', breadth of pileus 6"- 2'. Common.
