STUDIES OF AMERICAN FUNGI. 



in the Blue Ridge Mountains of North Carolina, during September, 

 1899. The plants are large, the caps 10-15 cm. broad, the stem 5-8 

 cm. long, and 2-3 cm. in thickness. 



The pileus is convex, umbilicate, then depressed and more or less 

 funnel-shaped in age, white, in the center roughened with fibrous 

 scales as the plant ages, the scales becoming quite stout in old plants. 

 The scales are tinged with dull ochraceous or are light brownish in 

 the older plants. The ochre colored scales are sometimes evident 

 over the entire cap, even in young plants. In young plants the 

 margin is strongly involute or inrolled, and a loose but thick veil of 



interwoven threads ex- 

 tends from the surface 

 of the roll to the stem. 

 This disappears as the 

 margin of the cap un- 

 rolls with the expanding 

 pileus. The margin of 

 the pileus is often ster- 

 ile, that is, it extends 

 beyond the ends of the 

 gills. The gills are 

 white, stout, and broad, 

 decurrent, some of them 

 forked near the stem. 

 When bruised, the gills 

 after several hours be- 

 come ochraceous brown. 

 The spores are sub- 

 globose, minutely 

 spiny, 8-12 yu. The stem 

 is solid, cylindrical.

mmutely tomentose, spongy within when old. 



The taste is very acrid, and the white milk not changing to yel- 

 low. While the milk does not change to yellow, broken portions of 

 the plant slowly change to flesh color, then ochraceous brown. Fig- 

 ures 123, 124 are from plants collected in one of the damp gorges 

 near Ithaca, during September, 1896. The forked gills, the strongly 

 inrolled margin of the cap and veil of the young plants are well 

 shown in the illustration. 



Lactarius chrysorrheus Fr. This is a common and widely distribu- 

 ted species, from small to medium size. The plants are 5-8 cm. high, 

 the cap 5-10 cm. broad, and the stem 1-1.5 cm. in thickness. It
