Report of the State Botanist. 131 



reddish-brown or chestnut color, fading with age to tawny-brown; 

 lamellae 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 .0005 in., milk copious, white, taste 

 mild. 



Pileus 3 to 5 in. broad, stem 3 to 5 in. long, 6 to 12 lines thick. 



Thin woe is. Sandlake, Gansevoort and Brewerton. August and 

 September. 



This curio.us Lactarius is related to L. volemus, from which it may be 

 separated by its darker colors and its corrugated pileus. The flexuous 

 reticulated rugae present an appearance similar to that of the hymenium 

 of a Merulius The pileus is everywhere piuinose-pubescent and the 

 lamellae bear numerous spine-like or acicular cystidia or spicules, .0016 

 to .002 in long, These are. so numerous on and near the edges of the 

 lamellae 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 ; lamellae broad, subdistant, yellowish ; stem equal, 

 stout, hollow, paler than or colored like the pileus ; spores subglobose or 

 broadly elliptical, .00035 to .00045 m *> niilk 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 lamellae are four or five lines broad and the 

 flesh is white or whitish. 



Lactarius rufus, Fr. 



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 broivn- 

 ish-red, shining; lamellae 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.
