due to meteorological conditions. The lamelle, though at first crowded, 
become more lax with the expansion of the pileus. They are generally 
a little broader toward the marginal than toward the inner extremity. 
Their tendency to deliquesce is often shown by their wetting the paper 
on which the pileus has been placed for the purpose of catching the 
spores. The stem is usually somewhat fibrous and striated but forms 
occur in which it is even and glabrous. When growing from the sides 
of stumps and prostrate trunks it is apt to be curved. Two forms deserve 
varietal distinction. 
Var. albus. Pileus and stem white or whitish. 
Var. albypes. Pileus cinereous yellowish or brown; stem white or 
whitish, destitute of blackish fibrils. 
In Europe there are three or four forms which have been designated 
as species under the names A. ragens, A. patricius, A. exvmius and Ay 
petasatus, but Fries gives them as varieties or subspecies of A. cervinus, 
though admitting that they are easily distinguished. None of these 
have occurred in our State. A. atricapillus, Batsch., A. latus, Bolt., 
A, Pluteus, Pers., and A. Neesvi, Kl., are given as synonyms of A. 
cervinus. 
Pluteus umbrosus, Pers. 
Shade-loving Agaric. Brown Pluteus. 
Pileus fleshy, at first campanulate, then convex or expanded, rugose 
wrinkled and more or less villose on the disk, fimbriate on the margin, 
blackish-brown ; lamellez broad, somewhat ventricose, at first whitish, 
then flesh- colored, blackish-brown and fimbriate or denticulate on the 
edge ; stem solid, colored like or paler than the pileus, fibrillose or 
villose-squamose ; spores elliptical, .co03 in. long, .ooo2 broad. 
Decaying wood and stumps, especially of pine, both in shaded and 
open places. Not rare. 
This is similar in size and general appearance to the preceding species, 
from which it is readily distinguished by the rugose-villose disk of ths 
pileus and the dark brown edge of the lamellae. The color of the pileue 
is usually darker than in that species. I have not seen it with the mar- 
gin fimbriate, though this is a prominent character of the species in 
Europe. 
Pluteus granularis, Peck. 
Granular Pluteus. 
Pileus convex or nearly plane, subumbonate, rugose-wrinkled, granu- 
lose or granulose-villose, varying in color from ‘yellow to brown ; lamel- 
le rather broad, crowded, ventricose, whitish, then flesh- colored ; 
stem equal, solid, colored like the pileus, often paler at the top, velvety. 
pubescent, rarely squamulose ; spores subglobose or broadly elliptical, 
-00025 to .0003 in. long, .o002 to .o0025 broad. 
Plant 1.5 to 3 inches high, pileus 1 to 2 inches broad, stem 1 to 2 
lines thick. 
Decaying wood and prostrate trunks in woods. Hilly and mountain- 
ous districts. June to September. 
The species is closely related to the two preceding, but is readily dis- 
tinguished from them by the peculiar vesture of the pileus and stem.
