DISTINGUISHING FIELD-MARKS : The rather large size and thick 
flesh of the plant, the glabrous, smooth, or sometimes rugose or 
cracked surface of the pileus, the fulvous to golden-fulvous color 
of both pileus and stem, the whitish gills which become brown 
where injured and in drying, and the abundant, mild, sticky latex. 
The latex drops from even slight wounds in the gills or flesh. 
There is a great variation in color in different specimens of L. 
lactiflua, but the other characteristics remain so constant that it 
seems scarcely possible to separate valid varieties upon the color 
basis. Two collections from Virginia (407 and 266 Murrill) are 
described as pale cream-color, while in North Carolina I found the 
color varying from pale-buff to a dark chestnut-red (Indian chest- 
nut-red, 333). This difference in color does not seem to be due 
to a shady or a sunny habitat. The rugose and the cracked 
character of the pileus, however, is probably due to weather con- 
ditions or to moisture content. In wet weather the pileus is more 
often rugose, while in dry weather the surface is liable to become 
cracked in areas. In North Carolina, while rain fell nearly every 
day the rugose condition prevailed, the plants with the cracked
