DISTINGUISHING FIELD-MARKS: The nearly plane pileus, with 
the margin remaining deflexed, the gray or brownish-gray zonate 4 
surface, the absence of viscidity, and the distant rather yellowish 
gills. In color it resembles both Lactaria circellata Fr. and Lac- 
taria flexuosa Fr., from the former of which it may be distinguished 
by the lack of viscidity, and from the latter by the persistently gla- 
brous surface, the more regular margin, and the less distant gills.

Mus. 42: 110. 1889 Ци.

close, adnate to slightly decurrent, rather narrow ; stem colored ` 
like the pileus or paler, spotted, equal, dry, glabrous, firm, soon 
hollow, 2-5 cm. long, 1-2 cm. thick ; flesh white ; spores creamy- 
white, subglobose, echinulate, 7-8 и; latex white, unchanging, but

DISTINGUISHING FIELD-MARKS : Lactaria atroviridis closely re- 
sembles Lactaria turpis (Weinm.) Fr., especially when dried, but 
in the fresh condition it may be distinguished from it by the 
absence of viscidity in wet weather, by its dark-green color, and | 
by the change in color of the wounded gills. 
The type specimens of this species аге in the herbarium of the | 
N. Y. State Museum at Albany. The species seems to be rare
