Ochrosporae 



P. margina'ta Batsch. marginatus, margined. PileilS i in. and Phoiiota. 

 more broad, honey-colored when moist, tan when dry, hygrophanous, 

 slightly fleshy, convex then expanded, obtuse, even, smooth, margin 

 striate. Stem about 2 in. long, 1-2 lines thick, tubed, equal, fibrillose 

 or slightly striate, not scaly, of the same color as tlie pileus, but becom- 

 ing dingy-brown, and commonly white velvety at the base. Ring 12 

 lines distant from the apex, often in the form of a cortina and fugacious. 

 Gills adnate, crowded, thin, narrow, at first pallid, then darker cinna- 

 mon. 



It varies much, and is deceptive on account of the vanishing veil. In 

 hedges there is a very small cespitose form with the pileus only K in. 

 broad, and the stem tough and smooth, with exception of the remains 

 of the fugacious cortina. There also occur on the ground among 

 mosses smaller and paler forms, which must be carefully distinguished 

 from A. unicolor, etc. Stevenson.

 Mcllvaine. 



The caps of this small Phoiiota, seldom over I ^ in. across, can be 

 gathered in goodly numbers where it frequents. They are of excellent 

 quality. 



P. dis'color Pk. changing color. Pileus thin, convex, then ex- 

 panded or slightly depressed, smooth, viscid, hygrophanous, watery- 

 cinnamon and striatulate on the margin when moist ; bright ochraceous- 

 yellow when dry. Lamellae close, narrow, pallid then pale rust-color. 

 Stem equal, hollow, fibrillose-striate, pallid. Ring distinct, persistent. 

 Spores elliptical, 7x5^.. 



Plant subcespitose, 2-3 in. high. Pileus 8-16 lines broad. Stem 

 i line thick. 



Old logs in woods. Greig. September. 



The change of color from the moist to the dry state is very marked. 

 This species resembles Agaricus autumnalis, in which the annulus is 

 fugacious and the spores are longer. The edge of the gills in both is 

 white-flocculose. Peck, 25th Rep. N. Y. State Bot. 



Two forms of this species are found. One has a scattered form of 

 growth, the other found on decaying wood of birch is cespitose. The
