This is the Largest and finest of the genus. Small individuals 

 may he confused with Tricholoma resplendens, but due regard to 



broader pileus, shinier stem and the waxy i;ills which are de- 



currenl in expanded plants, will distinguish it at once. 

 Microscopically the divergenl hyphae of the gills, as well as 

 the basidia, are a certain distinction. It has been met with for a 

 series of years, every autumn, and is consistently a large white 

 plant, SO l hat it can hardly he referred to //. pudorfntlS. When
