Thomas at Plandome, Long Island, September 15, 1912. The 
color of fresh specimens somewhat resembles that of Russula 
virescens, but the surface is darker green and both pileus and stipe 
are spotted, glabrous to the unaided eye, reticulate-appressed-fibril- 
lose under a lens. The lamellae are white, becoming olivaceous 
in spots ; the latex at first mild, slowly becoming decidedly acrid.

Plate 187. Figure 2. X i 
Pileus fleshy, convex, then plane, depressed at the center, some- 
times becoming infundibuliform, 4-10 cm. broad; surface yel- 
lowish-bufif, bistre, or fulvous, azonate, dry, very minutely 
pruinose-velvety, appearing as though pulverulent, sometimes 
rugose, sometimes rimose-areolate ; margin involute, then spread- 
ing or uplifted ; context firm, whitish, odorless, edible ; latex 
white, unchanging, not staining the flesh or lamellae brownish, 
mild ; lamellae whitish to cream-colored or yellowish-buflf, not 
discoloring where injured, not forking, distant, sometimes con- 
nected by rugose elevations, adnate to slightly decurrent, about 3 
mm. broad ; spores white, globose to broadly ellipsoid, minutely 
echinulate, 8-10 /x in diameter ; stipe of the same color as the 
pileus, nearly equal, glabrous, sometimes pruinose, stuffed and 
firm, 2-5 cm. long, 0.5-1. 5 cm. thick. 
On the ground in mixed woods throughout most of the eastern 
United States, but not so abundant as Lactaria lactiflua, which it 
much resembles. Its bright colors, velvety' surface, distant gills, 
and lack of odor should distinguish it. The flesh is of good flavor 
and edible ; the latex white, unchanging, mild, and very abundant. 
Lactaria luteola and Lactaria, suhvelutina are other closely related 
species. The poisonous Lactaria rufa is bay-red to rufous and 
very acrid.

Pileus convex to expanded, deeply depressed at the center, soli- 
tary, 7 cm. broad; surface distinctly viscid, glabrous, smooth.
