REPORT OF THE STATE BOTANIST. 131 
reddish-brown or chestnut color, fading with age to tawny-brown, 
lamellz close, dark cream color or subcinnamon, becoming paler when 
old, sordid or brownish where bruised or wounded , stem equal, solid, 
glabrous or merely pruinose, paler than but similar in color to the 
pileus ; spores subglobose, .0004 to .oo05 in., milk copious, white, taste 
mild. 
Pileus 3 to 5 in. broad, stem 3 to 5 in. long, 6 to 12 lines thick. 
Thin woods. Sandlake, Gansevoort and Brewerton. August and 
September. 
This curious Lactarius is related to L. volemus, from which it may be 
separated by its darker colors and its corrugated pileus. The flexuous 
reticulated rug present an appearance similar to that of the hymenium 
of a Merulius. The pileus is everywhere pruinose-pubescent and the 
lamellz bear numerous spine-like or acicular cystidia or spicules, .oo16 
to .oo2 in. long. ‘These are so numerous on and near the edges of the 
lamella that they give them a pubescent appearance. 
Lactarius platyphyllus, Peck. 
Broad-gilled Lactarius. 
Pileus depressed or subinfundibuliform, glabrous, zoneless, yellowish- 
incarnate or yellowish-red, the decurved or spreading margin sometimes 
wavy or flexuous; lamelle broad, subdistant, yellowish; stem equal, 
stout, Hollow, paler than or colored like the pileus; spores subglobose or 
broadly elliptical, .00035 to .o0045 in.; milk white, taste acrid. 
Pileus 4 to 8 in. broad, stem 3 to 5 in. long, 6 to 12 lines thick. 
Woods. North Elba. August. 
This large species is apparently very rare. It has been observed but 
once, and then in dry weather, so that it was not positively ascertained 
whether the pileus may not be viscid when moist. Its real position is, 
therefore, uncertain. The lamelle are four or five lines broad and the 
flesh is white or whitish. 
Lactarius rufus, /7. 
Red Lactarius. 
Agaricus rufus, Scop. 
Pileus convex and centrally depressed, then infundibuliform, gener- 
ally with a small umbo, glabrous, sometimes slightly floccose or pubes- 
cent when young, especially on the margin, zoneless, bay-red or brown- 
ish-red, shining; lamellz narrow or moderately broad, sometimes 
forked, close, subdecurrent, yellowish or reddish: stem nearly equal, 
firm, stuffed, paler than or colored like the pileus; spores white, .0003 to 
0004 in.; milk white, taste very acrid. 
Pileus 2 to 4 in. broad, stem 2 to 4 in. long, 3 to 5 lines thick. 
Low woods and swamps. North Elba. August. Rare. 
The red Lactarius is known by its rather large size, dark-red pileus 
and intensely acrid taste. It has been found but once in our State. 
The flesh is pinkish and the stem sometimes pruinose. It is designated 
by authors as very poisonous and extremely poisonous. Cordier even 
says that worms never attack it.
