Mus. 29: 44. 1878. 
Pilens fleshy, thin, broadly convex or nearly plane, then slightly depressed in the cen- 
ter, sometimes with a small umbo, 1.5-5 cm. broad ; surface at first umber tinged with lilac, 
fading, azonate, viscid in wet weather, quickly becoming dry, glabrous; margin inrolled 
and pruinose at first, then spreading, even: context fragile, tinted with umber, staining 
pale dull-green, then brownish where injured, odorless; latex white, unchanging, tardily 
but decidedly acrid; lamellae whitish or yellowish, becoming pale dull-green where in- 
jured, and at length brownish, some forking near the stipe, close, adnate to slightly 
decurrent, 2-4 mm. broad; stipe paler than the pileus, equal or slightly tapering upwards, 
glabrous or merely pruinose, stuffed, 1.5-5 cm. long, 4-10 mm. thick: spores white, sub- 
globose, slightly echinulate, 6.5-8 « in diameter. 
TYPE LOCALITY: New York. 
HABITAT: On decaying wood or on the ground in low moist woods. 
DISTRIBUTION : Vermont and New York. 
ExsiccaTi: Burl. Lact. N. Am. #47. 
XIII. Cinereae. Pileus of medium size; margin involute at first, naked; surface some 
shade of gray, viscid, glabrous: context lax, thin, fragile; latex white, unchanging, or 
staining the broken flesh gray or greenish, soon acrid ; lamellae becoming darker and prui- 
nose with age. 
44. Lactaria cinerea Peck, Ann. Rep. N. Y. State 
Mus. 24: 73. 1872. 
Pileus fleshy, thin, convex at first, soon umbilicate to depressed in the center, at length 
infundibuliform, 2-7 cm. broad; surface cinereous, darkest in the center, becoming pale 
toward the margin, fading, occasionally zonate, viscid when wet, glabrous; margin invo- 
lute at first, at length arched or uplifted, even: context fragile, white, not changing 
color; latex white, unchanging, very acrid after a few seconds; lamellae white, not chang- 
ing color where bruised, often appearing pruinose, especially in dried plants, a few forking 
within 1 or 2 mm. of the stipe, close, adnate, rather narrow; stipe of the same color as 
the pileus or paler, subequal but more often tapering upwards, frequently tomentose at 
the base, otherwise glabrous, spongy, soon hollow, 3-8 ctn. long, 8-16 mm. thick: spores 
white, subglobose, minutely echinulate, 5.5~7 « in diameter.

Pileus fleshy, thin, convex, then plane, depressed in the center, sometimes with a 
small umbo, 2.5-8 cm. broad; surface smoke-gray with umber shades, sometimes faintly 
zonate especially toward the margin, usually dry, but probably viscid in wet weather, } gila- 
brous, sometimes minutely roughened by pits which cause silvery reflections ; aiaroin in-
