 Fr. 



Woods. Adirondack region. August and September. 



This and R. obscura agree with R. decoloransin their 

 general characters, the most conspicuous difference between them 

 and it being the color of the pileus. This character in many species 

 is not thought to be of specific value, but in these plants the colors of 

 the pilei appear to be constant, nor do they become intermingled on 

 the same pileus as in other species with the pileus variously colored.
