II. Mycexa. — Pilens somewliat membranaceous; the margin at first 

 straiglit and appressed. Stipe horny, hollow, tough, dr^^; the 

 m3celiiira rliizomorphous. 



D. Pileus campanulate or convex. 

 g. Stipe glabrous, shining, 13. 



h. Stipe velvety or meah', 14, 15. 



E. Pileus soon umbilicate, 16, 17. 

 D. Pileus campanulate or convex. 



g. Stipe glabrous, shining. 



13. M. CAMPANDLATUS, Peck. — Pileus membranaceous, convex or 

 campanulate, dry, glabrous, plicate-sulcate, ochraceous-red, the disk a 

 little darker. Stipe horny, hollow, glabrous, shining, blackish-brown. 

 Lamellae attenuate-attached or nearl3^ free, distant, whitish. 



Growing on dead leaves in woods, common throughout the summer, 

 Pilens ^-f ths of an inch in diameter, the stipe 2-3 in. long. This is a very 

 elegant species, flourishing abundantly, and growing quite rank in our 

 rich woods. I find specimens sometimes with a pinkish tint. 



h. Stipe velvety or mealy. 



14. M. CLAV^FORMis, Berk'. — Pileus submembranaceous, convex 

 tough, white. Stipe tapering downward; below velvety, brown; above 

 white, lurfuraceous. Lamella long decurrent, broad in front, distant, 

 whitish inclining to flesh-color. 



On dead sticks in woods, Pileus 2 lines broad, stipe 1 in. long. 

 The stipe is attached by a minute bulb. The species is remarkable 

 for its very decurrent lamellae. It is one of the new species of Lea's 

 catalogue. 



15. M. NiGRiPES, Schw. — Pileus membranaceous, companulate, um- 

 bonate, striate, somewhat pellucid, pure white. Stipe somewhat bulbous, 

 black, white farinose. Lamellae adnate, arcuate, rather broad, pure 

 white, growing pale. 



Growing among leaves and on the ground in woods. Stipe 1^ in. 

 in length, black but wholly covered over with a white meal which may 

 be easily rubbed off. It is closely related to M. alliacens, Jacq., but is 

 inodorous. I am indebted to Mr. Stevenson for the copy of the 

 original description. 



E. F ileus soon umbilicate. 



16. M. ROTDLA, Scop. — Pileus membranaceous, a little convex, um-
