upon exposure to the air. The color of the plant becomes a deeper 
yellow in drying. It may be distinguished from Г. /лс иа by its 
smaller size, the velvety, more yellow pileus, and by the different 
odor. It resembles Z. hygrophoroides more closely, but can be 
separated from that by the close gills, and by the brown color 
which the milk and wounds assume. 
After further collections of Г. /ueo/a, Professor Peck now con- 
siders Z. foetidus Peck to be the same species, having found that 
Г. luteola sometimes has a fetid odor; accordingly, L. foetidus is 
reduced to а synonym. The type specimens are in the herbarium 
of the N. Y. State Museum at Albany.

1904. (Ав Lactarius] 
Pileus fleshy, firm, convex then nearly flat, depressed in the 
center, golden-fulvous, dry, minutely velvety, appearing pruinose 
to the naked eye, sometimes wrinkled, 2.5—5 cm. broad, margin 
inrolled, then spreading, even, sometimes wavy; gills Cream: 
colored, becoming darker with age, not staining brown where 
injured, a few forking, close, adnate to slightly decurrent, narrow ; 
stem of the same color as the pileus or paler, equal, somewhat 
velvety, smooth, solid, 1-2 cm. long, 4-8 mm. thick ; flesh white,

; DISTINGUISHING FIELD-MARKs: The close gills and the unchang- 
ing white latex which does not stain the gills brown. 
The dried specimens of this plant closely resemble those of 
L. luteola Peck, but the spores are smaller and smoother.
