rileus ll(\sli,>, liriii, convex or nearly plane, Honietinies um- 

 bilicately depressed in the center, pruinose, more or less rugose, 

 yellowish or buff color, flesh white, becoming brown where 

 wounded, taste mild, milk copious, white or whitish, changing to 

 brown; lamellae close, adnate or slightly rounded behind, whitish, 

 becoming brown where wounded; stem short, equal or tapering 

 downward, firm, solid or someAvhat spongy within, white or buff 

 color ; spores white, globose, .0003 of an inch broad. 



The yellowish lactarius is a very distinct species, easily known 

 by its buff color, copious white milk, changing to brown on ex- 

 posure to the air, and by its minutely velvety cap, which to the 

 naked eye has a pruinose appearance. The cap is broadly convex 

 or nearly flat when mature, sometimes with a slight central de- 

 pression. Its surface is seen by the aid of a lens to be covered 

 with a minute velvety pubescence, which is soft to the touch and 

 when moist is slightly sticky. The surface is sometimes even 

 but more often rugose. Occasionally there is a narrow encircling 

 furrow or band near the margin. The color is whitish, buff or 

 yellow buff, becoming more pronounced in drying. The flesh is 

 white or whitish. Wounds of any part of the plant assume a 

 brown color. The gills are narrow, closely placed, attached to 

 the stem but scarcely decurrent on it, whitish. The stem is short, 

 cy lindric or rarely tapering downw^ard, solid or somewhat spongy 

 Ik the center and colored like the cap. 



The cap is 1.5-3 inches broad; the stem is 1-1.5 inches long, 

 3-5 lines thick. The plant grows in a scattered manner among 

 fallen leaves in woods and appears in August. Lactarius 

 foetidus, the fetid lactarius, is closely related and may yet 

 prove to be a mere variety having a strong disagreeable odor and 

 less copious milk.
