toward the base. They have a fibrous texture externally and are 
smooth and somewhat shining. In our specimens they are brown 
and darker than the cap. 
The cap is I to 2 \ in. broad, the stem is 3 to 4 in. long and 
2 to 4 lines thick. 
The plants grow under trees and appear in September. In Ohio 
s . 
the typical form is said to grow from spring till late autumn and to 
form clusters of 20 to 50 individuals. 
The flavor seems to me to be superior to that of the honey-colored 
armillaria. 
Hygrophorus flavodiscus Frost 
Yellow-disked Hygrophorus 
Plate 51, fig. 6-11. 
Pileus fleshy, convex or nearly plane, glabrous, very viscid or 
glutinous, white, pale yellow or reddish yellow in the center, flesh 
white; lamellae adnate or decurrent, subdistant, white, sometimes 
with a slight flesh-colored tint, the interspaces sometimes venose; 
stem subequal, solid, very viscid or glutinous, white at the top, 
white or yellowish elsewhere; spores elliptic, white, .00025 to .0003 
in. long, .00016 to .0002 broad. 
The yellow-disked Hygrophorous scarcely differs from the sooty 
Hygrophorous in any respect except in color. It is sometimes found 
growing with it in pine woods. Both appear late in autumn. The 
cap is rather thick and fleshy in the center but thin at the margin. 
It is so very viscid or glutinous that when dry its surface is smooth 
and shining as if varnished. The color of the disk is yellowish or 
reddish yellow but the margin is white. 
The interspaces between the gills are distinct and sometimes are 
marked by cross veins. The gills are white or nearly white and are 
attached to the stem or run down upon it. 
The stem is solid and externally glutinous except a short space 
at the top. { 
The cap is 1 to 3 in. broad, the stem 1 to 3 in. long and from 
i to J an in. or more thick.
