attached, close, white changing to brown. Spores brown, sometimes 
inclined to be irregular in shape, .008X.005 mm. 
Upon lawns, on grassy places along paths; sometimes very abund- 
ant after rains in spring, and the forepart of summer. Pileus 14-3 in. 
in diameter, stipe 2-4 in. high. Pileus white or pale-tawny, sometimes 
yellowish; stipe somewhat flexuous, equal or tapering downward, white 
or shaded with buff; the annulus often dependent in fragments from 
the edge of the pileus. 
B. Lignatile or epiphytal, generally cespitase. 
a. Pileus scaly, not hygrophanous, 
a’. Lamelle at first whitish. 
93. A. SQUARROSOIDES, Peck.—Pileus firm, convex, viscid when 
moist, at first densely covered by erect papillose or subspinose tawny 
scales. Stipe equal, firm, stuffed, rough with thick squarrose scales, 
white above the thick floccose annulus, pallid or tawny below. 
Lamelle close emarginate, at first whitish, then pallid or dull cinna- 
mon. Spores elliptic, ferruginous, .005.004 mm. 
Dead trunks and old stumps of maple in woods, in autumn. 
Densely cespitose; pileus 2-4 in. broad, stipe 3-5 in. long. This 
species is closely related to A. squarrosus, with which it has no doubt 
been confused; but the latter is dry, not viscid, and is differently 
colored. I take this to be the A. squarrosus of Lea’s Catalogue. 
94, A. LIMONELLUS, Peck.—Pileus thin, convex or expanded, some- 
what umbonate, viscid, rough with scattered erect reddish-brown scales, 
lemon-yellow. Stipe equal, solid, rough with revolute or recurved 
scales, pallid or yellowish; the annulus lacerate, Lamellze narrow, 
close, rounded behind, whitish. Spores elliptic, fercuginous, .006.005 
mm. 
Prostrate trunks of beech, in woods. Cespitose; pileus 1-2 in. 
broad, stipe 2-3 in. long. This species is easily distinguished by its 
lively lemon-yellow color. The reddish-brown scales on the surface of 
the pileus finally become scattered and remote. 
95. A. ALBOCRENULATUS, Peck.—Pileus fleshy, firm, convex or cam- 
panulate, somewhat umbonate, viscid, rough with dark-brown or 
blackish floceose scales, yellowish-brown. Stipe firm, nearly equal, 
stuffed or hollow. white above the evanescent annulus, scaly and 
pallid below. Lamelle broad, rather distant, emarginate, the edge 
white-crenulate, grayish, then ferruginous. Spores somewhat elliptic, 
rather acute at each end, .011.006 mm.
