LACTARIAE OF THE UNITED STATES 89 
bruised, dry, somewhat velvety, 2.5-3.8 cm. broad, margin invo- 
lute, then spreading, even ; gills pallid, becoming darker, brownish 
in drying, close, adnate to decurrent; stem white, salmon-colored 
within, nearly equal, occasionally eccentric, velvety, solid, about 2.5 
cm. long, 3-6 mm. thick ; flesh becoming salmon where wounded ; 
spores subglobose, echinulate, 7.5-0/4; latex salmon-colored. 
Has.: In wet swampy places, usually on naked ground that 
has been overflowed. August to October. 
DISTRIB. : Alabama, Ват (type) ; Mississippi, Zarte. 
DISTINGUISHING FIELD-MARKS: The white color of the plant, 
the velvety covering, the short stem, and the salmon-colored latex. 
This isthe only known species having from the first salmon-col- 
ored milk. I have not seen this plant living and I am in doubt as 
to its relationship. The dry velvety pileus and the salmon color 
assumed by wounds would indicate a relationship with the P/intho- 
galae, while the colored milk would tend to place it with the 
Dapetes. 
DOUBTFUL SPECIES 
LACTARIA ACRIS (Bolt.) Fr. Ерісг. 342. 1838. [As Lactarius.] 
— Hennings, in EN & Prantl, Nat. Pflanzenfam. 
**: 216. 1898 
This European species has been reported from North Carolina 
by Schweinitz in Syn. Fung. Carol. Super. 60. 1818, but the 
specimens have been destroyed by insects, and, since this is the 
only station for which it has been reported, I hesitate to include it 
in the list of species positively known in the United States. Из 
relationship seems to be with Lactaria plinthogala. Thedistinguish- 
ing marks are the ill odor, the spotted pileus, and the more red- 
dish color assumed by the acrid latex. Itis well figured in Cooke, 
Br. Fungi, p/. 1005. 
XVI. LacrIFLUAE 
Pileus dry, glabrous or velvety, some shade of fulvous, flesh 
rather thick Set firm ; gills becoming darker with age and pruinose ; 
latex abundant, sweetish or at least mild, unchanging, but the gills 
and flesh sometimes becoming brown where injured. 
The members of this group seem to be very closely related, 
the species, in one instance, differing chiefly in the reaction of the 
wounds upon exposure to the air. With the exception of the first 
two, the species are all confined to America. T
