DISTINGUISHING FIELD-MARKS: Lactaria deliciosa varies іп 
color from orange to pale-yellow and is sometimes conspicuously 
zonedand again nearly azonate, but the coloris always brighter and 
the zones are usually more marked than in Lactaria Chelidonium, 
and, while the latex may at first be saffron-yellow, it soon becomes 
red-orange and is always abundant. The color and the zonation 
of the pileus are most decided in the young plant. The change in 
the color of wounds from orange to greenish is often rapid, the 
whole plant becoming greenish where bruised or as it becomes 
old. At other times I have not been able to detect any greenish 
tint to the gills or other parts of the plant either with age orinjury. 
The green color was very prominent in the specimens sent from 
Florida by Fawcett and it persisted in the dried mushroom,
