Lactarius regalis, Peck. 
Pileus convex, deeply depressed in the center, viscid when moist, often 
corrugated on the margin, white tinged with yellow; lamellae close, decur- 
rent, whitish, some of them forked at the base; stem stout, short, equal, 
hollow, smooth ; taste acrid; milk sparse, white quickly changing to sulphur- 
yellow ; spores .0003’. 
Plant 4'-6' high, pileus, 4'-6’ broad, stem 1' thick. 
Ground in woods. Croghan. September. 
This interesting plant rivals ZL. piperatus in size and closely 
resembles it in general appearance, but the viscid pileus and sparse 
milk quickly changing to yellow, as in L. chrysorrheus, clearly 
distinguish it. 
Lactarius Geradii, Peck. 
Pileus expanded or centrally depressed, dry, rugose-wrinkled, often with a 
minute umbo or papilla, sooty-brown, the thin spreading margin sometimes 
wavy or irregular; lamellae broad, distant, decurrent, white, the interspaces 
uneven; stem equal, solid, colored like the pileus; flesh and spores white ; 
taste mild ; milk white and unchangeable. 
Plant 3’-5' high, pileus 2'-4' broad, stem 4-6” thick. 
Ground in woods and groves. Poughkeepsie, W. R. Gerard. 
Albany and Croghan. September. 
In the color of the pileus and stem, this species is like the large 
variety of L. fuliginosus, but its real relationship is with L. distans, 
from which it is separated by its color and its longer equal stem, 
characters which may prove to be only varietal. 
Russula sordida, Peck. 
Pileus firm, convex, centrally depressed, dry, sordid white, sometimes 
clouded with brown; lamellae white, some of them forked; stem equal, 
solid, concolorous; spores globose, .0003'; taste acrid; flesh changing color 
when wounded, becoming black or bluish-black. 
Plant 4'-5' high, pileus 3'-5' broad, stem 6/12” thick. 
Ground under hemlock trees. Worcester. July. 
The whole plant turns black in drying. 
Marasmius semihirtipes, Peck. 
Pileus thin, tough, nearly plane or depressed, smooth, sometimes striate on 
the margin, hygrophanous, reddish-brown when moist, alutaceous when dry, 
the disk sometimes darker; lamellae subdistant, reaching the stem, slightly
