106 LACTARIAE OF THE UNITED STATES 
` sometimes glistening pileus, the change in the color of Ше 
wounded .gills and the lack of odor will help to determine it. In 
color it often approaches Г. parva Peck, but, judging from the 
specimens of the latter which I found in Vermont and the type 
specimens of Z. varia, the two species are plainly distinct, although 
closely related. Тһе type specimens of 2. varia are a pale gray, 
while Z. parva remains some shade of umber when dried. As I 
have not seen L. varia living, I have arranged the above descrip- 
tion from the original description and some additional notes from 
Professor Peck and from observation of the type specimens which 
are in the herbarium of the New York State Museum at Albany. 
DOUBTFUL SPECIES 
LACTARIA ILLACHRYMANS Berk. & Rav. Berk. & Curt. Ann. and 
Mag. Nat. Hist. П. 12: 425. 1853. [As Lactarius | 
“Small; pileus thin, firm, convex to plane, then umbilicate, 
pale-fulvous, obscurely two- to three-zonate ; stipe solid, white ; 
lamellae white, crowded, narrow, subdecurrent, not milk-bearing 
when broken ; taste slightly aromatic, subacrid.” 
Has. and Loc.: In swamps in South Carolina, Ravenel. 
This species has been reported also from North Carolina by 
Curtis. I have not seen the type specimens, but the coloration 
and zonation given in the above description would indicate that 
the species belongs to the Lactariae, and that the absence of milk 
may have been due to the age of the plant or to the fact that when 
the milk is scanty it will exude only immediately as a vigorous 
mushroom is collected. I would suspect that this number repre- 
sented a form of some plant which is under favorable and normal 
conditions latex-bearing. 
LACTARIA ALBIDA Peck, Rep. N. Y. St. Mus. 38: 126. 1885. 
[As Lactarius] 
" Pileus thin, plane or slightly depressed, glabrous, dry, white ; 
lamellae subdistant, adnate or slightly decurrent, white, the inter- 
Spaces venose; stem equal, solid, glabrous, white ; spores white, 
0003 to .00035 in.; milk white, taste acrid.” 
I have not seen this growing and the dried plant specimens do 
not show distinguishing characteristics, Professor Peck says ІП 4
