Syll., p. 455. Pileus white, 3-5 inches (7.5-12 centimeters) broad, 
fleshy throughout, firm, umbilicate then infundibuliform, regular, 
everywhere even, smooth with a whitish luster, the involute margin 
without strim; flesh firm, juiceless, not very thick, white. Stem curt,

even, smooth, white. Gills decurrent , thin , distant , very unequal, white, 
exuding small watery drops in wet weather. 
“ The stature and unchangeable colors are wholly those of L. vellereus 
and L. piperatus 7 but it is readily distinguished by the gills being juiceless , 
though they exude watery drops when young. In mixed woods. Un¬ 
common. September-October. Name— delicus, weaned ; without juice 
or milk in the gills, as distinguished from L. vellereus , etc. (Fr., Monogr.,

juiceless variety of Lact. vellereus its mild taste alone furnishes a separat¬

A large, coarse species, cup-shaped at maturity. I have found it in 
several localities in Massachusetts in July and August. It is of fair 
quality, cooked, but much inferior to 11. virescens , etc. Minnesota, in 
woods, August, Johnson; New York, Peck, 32d Eeport; California, Hark-

p. 05; Sacc., Syll., p. 459. Pileus 3-5 inches (7.5 centimeters) broad, firm, 
convex, centrally depressed, dry, sordid white, sometimes clouded with 
brown; gills close, white, some of them forked. Stem 4-5 inches (10-12.5 
centimeters) long, inch (12-24 mm ) thick, equal, solid, concolorous; 
spores globose, .0003 inch (7.5/^); taste acrid, flesh changing color

‘‘Ground under hemlock trees, Worcester, July. 
“ It resembles L. piperatus in general appearance. The whole plant 
turns black in drying. 
“A large form of this species was found growing under hemlock trees 
at Gansevoort. The pileus was 4-8 inches (10-20 centimeters) broad, 
at first white or whitish, umbilicate or centrally depressed; then more 
or less stained with smoky-brown or blackish hues and subiufundibuli- 
form. The flesh is white and taste mild ; the stem is short, 1-2 inches 
(2.5-5 centimeters) thick, solid, white, and somewhat pruinose; the 
gills are distant, unequal, very brittle, tinged with yellow. Every part 
of the plant turns blackish or violaceous black where wounded. By 
this character it is distinguished from R. nigricans , in which the flesh at 
first becomes red where broken.” 41st Eep. Peck. Found also in Ohio 
by Professor Morgan, under beech trees in hilly woods.
