LACTARIAE OF THE UNITED STATES 105 
pruinose, stuffed, 1.5-5 cm. long, 4-10 mm. thick ; flesh tinted 
with umber, staining pale dull-green, then brownish where injured, 
odorless; spores white, subglobose, slightly echinulate, 6.5-8 и; 
latex white, unchanging, tardily but decidedly acrid. 
Han: In woods on decaying wood. August and September. 
Distris.:, New York, Peck (type); Vermont, Burlingham 
101, 1906. 
The plant has been collected also by Guillet in Toronto, 
Canada. 
DISTIN FIELD-MARKS: The pale dull-green color which 
the wounded gills slowly assume serves to separate this species 
from the other members of this group with the exception of L. 
varia. It may be distinguished from the latter by its smaller size, 
the prevailing umber color of the pileus and stem, and the per- 
fectly glabrous, smooth surface of the pileus. For the most part 
Г. parva grows on decaying wood іп moist woods, while Г. varia 
grows on the ground. 
The type specimens are in the herbarium of the N. Y. State 
Museum at Albany.

Pileus fleshy, thin, convex, then plane, depressed in the center, 
sometimes with a small umbo, gray to brown, often with lilac tints, 
azonate, or rarely narrowly zonate on the margin, not viscid when 
ing pale dull-greenish where wounded, close, adnate to decurrent ; 
stem of the same color as the pileus or paler, equal, glabrous, 
stuffed, firm or spongy, 2.5-6 cm. long, 4-8 mm. thick ; flesh 
white, odorless; spores white, 7-8 м; latex white, unchanging, 
slowly acrid. 
Нав. : On the ground in moist woods. September. 
Distris.: New York, Peck (type); Vermont, Jones; Massa- 
chusetts, Davis; New Jersey, Sterling. 
DISTINGUISHING FIELD-MARKS: This species 
color that that characteristic alone cannot serve to distinguish it, 
but the prevailing gray color together with the glabrous, dry, 
varies so much in
