46 LACTARIAE OF THE UNITED STATES 
slightly tomentose at first, soon naked ; gills whitish, close, adnate 
to decurrent, narrow; stem whitish, not spotted, obscurely rugu- 
lose-reticulated, 2.5-4 cm. long, 12-16 mm. thick; spores sub- 
globose; latex white, unchanging, tardily acrid. 
Нав.: Pine groves. August. 
DISTRIB.: New York, Peck. 
I have not seen this plant living, and the above description is 
arranged from the original description and from the dried specimens. 
The type specimens are in the herbarium of the N. Y. State 
Museum at Albany. Тһе plant has not been found since the type 
collection and the dried specimens so closely resemble Г. ай 
Peck as to be indistinguishable from that species and at present I 
am inclined to regard it as the same.

This species has been reported from Connecticut by White on 
the basis of specimens collected by Hanmer, and from Minnesota 
by Johnson. I have seen the Hanmer specimens and they are all 
Lactaria turpis (Weinm.) Fr. The Johnson specimens are not 
available for examination. For these reasons I omit this species 
from the list of our known Lactariae. А description of the species 
is given in McIlvaine's One Thousand Am. Fungi. The following 
may further help in the recognition of the species should it be 
found and will also enable one to avoid confusing it with related 
species. 
DISTINGUISHING FIELD-MARKS : The grayish-green viscid pileus, 
zoned with drop-like concentric spots. It may be distinguished 
from Lactaria turpis (Weinm.) Fr. by the paler-green color, by 
the more inconspicuous down on the margin of the pileus and the 
otherwise glabrous surface and by the wounds of the gills turning 
cinereous. The gills do not become blackish in drying as do those 
of L. turpis. Regarded as poisonous. 
УТ. AsPIDEAE 
Pileus very viscid when young or in wet weather, and the 
margin minutely tomentose or pruinose-downy to nearly glabrous | 
* The name of this species should be Lactaria aeruginea ( Lamarck )
