equal, hollow, glabrous, pallid. Lamelle narrow, crowded, neariy free, 
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 is closely related 
to A. dryophilus ; both are common in Este’s woods, where the observer 
will readily distinguish them apart. The yellowish color of the pileus 
is seldom uniform ; sometimes itis in streaks or patches, sometimes 
spread over the disk, leaving a pallid margin. 
48. A. coLtorEus, Peck.—Pileus convex, then explanate and umbili- 
cate, somewhat fibrillose, hygrophanous, yellow, sometimes tinged with 
red. Stipe hollow, glabrous, yellow, with a long crooked villous root. 
Lamellz moderately close, emarginate, yellow. Spores .0083 mm. long. 
Among decaying leaves and wood, solitary or subceespitose. Pileus 
4-1 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 lamelle. 
B. Stipe velvety, floccose or pruinose. 
c. Lamelle broad, distant. 
49, A. VELUTIPESs, Curt.—Pileus fleshy, thin, convexo-plane, obtuse, 
glabrous, viscid. Stipe stuffed, velvety, reddish-black, rooting. 
Lamellz 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 cespitose, commonly ascending, 
sometimes excentric. Pileus 1-3 in. broad, slimy, and of a beautiful tawny 
cglor; stipe 2-5 in. long incurved, of a rich tawny brown, pale above. 
50. A. stipirarius, Fr.—Pileus a little fleshy, convexo-plane, um- 
bilicate, velvety-scaly or brown-fibrillose. Stipe stuffed then hollow, 
tough, brown, hirsute-fibrillose. Lamellz seceding free, ventricose, 
rather distant, white. 
Upon sticks, roots of grasses, etc., gregarious. Pileus 4-5 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 
fibres which sometimes form scales. | 
51. A. zonatus, Peck.—Pileus thin, fleshy, convex then expanded,
