B. Milk colored from the first. 
9. L. pEticrosus, Linn.—Pileus fleshy, convex, umbilicate, viscid, 
zonate, glabrous, somewhat orange-color, expallent, the margin 
glabrous. Stipe stuffed, then hollow, spotted. Lamellz somewhat 
decurrent, saffron-color, but expallent and greenish when wounded; 
the milk aromatic, saffron-red. 
In damp woods. Pileus 3-4 in. broad, stipe 14-3 in. long. The 
whole plant abounds with orange milk, and when bruised or old ex- 
hibits stains of green. 
C. Lamelle pallid then changing to a darker color, finally 
white-pruinose; milk white. 
d. Pileus viscid from the first. 
10. L. cinereus, Peck.—Pileus fleshy, at length expanded, centrally 
depressed, usually umbilicate, glabrous, viscid, light gray, with the 
disk sometimes u little darker. Stipe tapering upward, stuffed, con- 
colorous. Lamelle close white; the milk white acrid. 
In woods. Pileus !3-3 in. broad, stipe 2-4 in. long. This seems to 
be a larger plant than Prof. Peck’s, and I often find the pileus zonate, 
yet it does not seem to me to differ sufficiently to make a new species. 
11. L. vietus, Fr.—Pileus fleshy, thin, at first somewhat umbonate, 
viscid, afterward applanate, umbilicate, even, not zonate, when dry 
finely silky, expallent. Stipe stuffed then hollow, fragile, livid. 
Lamelle somewhat decurrent, thin, whitish ; mill at first white then 
changing to gray, tardily acrid. 
In humid woods. Pileus 2-4 in. broad, stipe 2-3 in. high. A very 
distinct species, thin, soft, frayile and various in form; the pileus 
sometimes infundibuliform, flesh-color or livid then gray. 
e. Pileus scaly, villous or pruinose. 
12. L. pistans, Peck.—Pileus fleshy, firm, convex or expanded, de- 
pressed, pruinose-tomentose, yellowish-tawny. Stipe very short, solid, 
firm, equal or tapering downward, pruinose, nearly of the color of the 
pileus. Lamelle distant, somewhat arcuate, white or yellowish; 
milk white, mild. 3 
In grassy ground. Pileus 2-4 in. broad, stipe 1-2 in. high. The 
pileus is sometimes irregular and excentric, and the cuticle often 
cracks into areas. 
J. Pileus polished, glabrous. 
13. L. votemus, Fr.—Pileus fleshy, compact, rigid, plano-depressed,
