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 L. 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 Q"-12" thick. 



Ground under hemlock trees. Worcester. July. 

 The whole plant turns black in drying. 



Marasmlus semihirtipesj 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
