equal, hollow, glabrous, pallid. Lamellfe narrow, crowded, nearly fi'ee, 

 pallid, spores white, curved, .008 mm. long. (See Plate V.) 



Growing among the fallen leaves in the woods from spring to 

 autumn. Pileus 1-2 in. across, stipe 2-3 in. high. It isclosel}^ related 

 to A. dryojJhilus ; both are common in Este's woods, where the observer 

 will readily distinguish them apart. The ^-ellowish color of the pileus 

 is seldom uniform ; sometimes it is in streaks or patches, sometimes 

 spread over the disk, leaving a pallid margin. 



48. A. coLOREUs, Peck. — Pileus convex, then explanate and umbili- 

 cate, somewliat fibrillose, h3'grophanous, yellow, sometimes tinged with 

 red. Stipe hollow, glabrous, yellow, with a long crooked villous root. 

 Lamellffi moderately close, emarginate, j'^ellow. Spores .0083 mm. long. 



Among decaying leaves and wood, solitary or subcsespitose. Pileus 

 |-1 in. broad, stipe 1-2 in. long without the root. The plant I have 

 here described comes so near Prof. Peck's plant, that I have so referred 

 it, although his description does not cover some of its marks. It re- 

 sembles A. cirrhatus in size and general appearance, but maintains a 

 uniform pale yellow color of stipe, pileus and lamellae. 



B. Stipe velvety, Jioccose or pruinose. 

 c. Lamella} broad, distant. 



49. A. VELUTiPES, Curt. — Pileus flesh}', thin, convexo-i)lanc, obtuse, 

 glabrous, viscid. Stipe stuffed, velvety, reddish-black, rooting. 

 Lamellas attached, distant, yellowish. Spores .006-.008 mm. long. 



Common on and about stumps and trunks in woods, at the foot of 

 posts, along fence rows, etc.; appearing late in autumn and persisting 

 through the winter, new plants appearing with a mild spell of moist 

 weather, until spring. Somewhat ca'spitose, commonly ascending, 

 sometimes excentric. Pileus 1-3 in. broad, slimy, and of a beautiful tawny 

 color; sti[)e 2-5 in. long incurved, of a rich tawnj' brown, pale above. 



50. A. STiPiTARius, Fr. — Pileus a little flesh}', convexo-plane, um- 

 liilicate, velvety-scaly or brown flbrillose. Stipe stuffed then hollow, 

 tough, brown, hirsutc-fibrillose. Lamellae seceding free, ventricose, 

 lather distant, white. 



Upon sticks, roots of grasses, etc., gregarious. Pileus \-^ an inch 

 broad, the stipe 1-2 in. long. A very singular Agaric, with the habit 

 of a Marasmius. Pileus whitish, clothed with tawny or brown hairs or 

 rtbres which sometimes form scales. 



51. A. zoNATUS, Peck. — Pileus thin, fleshy, convex then expanded,
