REPORT OF THE STATE BOTANIST. 129 
Lactarius lignyotus, /7. 
Sooty Lactarius. 
Pileus broadly convex plane or slightly depressed, dry, with or with- 
out a small umbo, generally rugose-wrinkled, dark-brown, appearing 
subpulverulent or as if suffused with a dingy pruinosily, the margin 
sometimes crenately lobed and distinctly plicate ; lamellz moderately 
close or subdistant, adnate, white or yellowish, slowly changing to 
pinkish-red or salmon color where wounded ; stem equal or abruptly 
narrowed at the apex, even, glabrous, stuffed, colored like the pileus, 
sometimes plicate at the top; spores globose, yellowish, .00035 to 
-00045 in.; milk white, taste mild or tardily and slightly acrid. 
Var. tenuipes. Pileus about 1 inch broad, stem slender, 2 to 3 in. 
long and about two lines thick. 
Pileus 1 to 4 in. broad, stem 1 to 3 in. long, 2 to 6 lines thick. 
Wet or mossy ground in woods and swamps. Adirondack mountains 
and Sandlake. July and August. Not rare in hilly and mountainous 
districts. 
The sooty Lactarius is closely related to the preceding species with 
which it was formly united by Fries as a variety, but from which it may 
be distinguished by its larger size. darker color and generally rugose- 
wrinkled pileus. Wounds of the flesh and lamellz slowly change color. 
as In that species, and, according to the description given by Fries, the 
milk also undergoes a similar change, but I have not been able to verify 
this in the American plant. According to the description of L. subto- 
mentosus, B. & R., the milk in that plant changes from white to 
yellowish and the taste is acrid. In the Twenty-third Report our plant 
was erroneousl~ referred to that species. 
Lactarius Gerardii, Peck. 
Gerard’s Lactarius. 
Pileus broadly convex plane or slightly depressed, dry, generally 
rugose-wrinkled, with or without a small umbo or papilla, dingy-brown, 
the thin spreading margin sometimes flexuous lobed or irregular; 
lamelle distant, adnate or decurrent, white or whitish, the interspaces 
generally uneven ; stem subequal, stuffed or hollow, colored like the 
pileus; spores globose, white, .00035 to .o0045 in.; milk white, wachange- 
able, taste mild. 
Pileus 1.5 to 4 in. broad, stem 1 to 2 in. long, 3 to 6 lines thick. 
Woods and open places. Poughkeepsie. W. &. Gerard. Greenbush, 
Sandlake and Croghan. July to September. 
This Lactarius closely resembles the sooty Lactarius in color, but 
differs from it in its more distant lamella, white spores and constantly 
mild taste. Wounds of the flesh and lamelle do not become pinkish- 
red as in that plant. From the next species its darker color, hollow 
stem and more globose rougher spores separate it. 
Lactarius hygrophoroides, B. & C. 
Hygrophorus-like Lactarius. Distant-gilled Lactarius. 
Lactarius distans, Pk. 
Pileus firm, convex or nearly plane, umbilicate or slightly depressed, 
rarely infundibuliform, glabrous or sometimes with a minute velvety
