DISTINGUISHING FIELD-MARKS : The whitish lily-shaped azonate 
pileus with a fringe-like white tomentum on the extreme margin, 
and the very rapid change in the color of the latex from white to 
sulphur-yellow. Іп the mature plant the tomentum is often lack- 
ing. The specimen found in Vermont was growing under a small | 
spruce on the edge of a wood in a somewhat mountainous district. 
Near the edge of the pileus were four or five faint ridges or corru- 
gations running parallel to the margin. 
In Мопорг. 2: 152, Fries says of the stem “sud lente pube 
tenuissima vix perceptibili tectus" In other places the stem is 
described as villous, but the statement in the Monograph is the 
more accurate. Our specimen, however was simply pruinose, and 
it is probable that the scarcely perceptible down mentioned by 
Fries was little more than a pruinosity, although there might be а 
variation in the nature of the covering under different environmental 
conditions.
