 white pines. Both collections made September 2, 1917. Color (of

 bruised ; yellowish olivaceous when dry. Spores as above.

Plates 50, 67, and 88 



Plants of medium to small size, but of slender, delicate habit, 

 gregarious and single or clustered and often partly fused; about 

 4-10 cm. hisrh and 2-8.5 cm. broad; stalk distinct, 1-2 cm. 

 long, 3-12 mm. thick, smooth, not rooting but deliquescing soon 

 into the white, membranous and fibrous mycelium ; main branches 

 spreading, their subdivisions turning upward and ascending in a 

 crowded manner, the ultimate branches very numerous and slender 

 and simple or toothed, the tips all pointed; all parts smooth and 

 terete; color when young a light buffy yellow, between chamois 

 and buff-yellow of Ridgway, the tips remaining this color until 

 maturity, lower parts soon becoming a darker honey-yellow or 

 isabella color and finally the whole thus colored, the base white 

 where protected by leaves, but becoming flesh color then brown 

 when bruised. Flesh rather toughish and not brittle, pale with a 

 tint of the surface color, becoming distinctly flesh-pink when cut; 

 taste distinctly bitter, odor none. In drying the plant becomes a 

 deep brown, about Dresden brown of Ridgway, and nearly the 

 color of dried C. abietina. There is a distinct contrast in color 

 when dry between the hymenium and the sterile areas in the angles, 

 which are darker. 



Spores (of No. 2769) about pip-shaped, minutely but distinctly 

 spinulose-warted, deep buffy yellow (about chamois color of 

 Ridgway), 2.5-3 x 5-6.5[x. Basidia 4.8x22^, with 4 curved 

 sterigmata. 



Among rotting leaves in deciduous woods. Known at present 

 with certainty only from Chapel Hill and from Vaughns, N. Y.
