LACTAEIUS. 17 



In woods. 



Entirely wliito; milk white, abundant, very acrid 

 Closely allied to L. piperatus, but differing in the longer, 

 stuffed stem attenuated downwards, thinner pileus, and the 

 adnate, very much crowded and very narrow gills that soon 

 become straw-colour. 



The milk is very abundant in the flesh, scanty in the 

 gills. (Fries.)

 as thick, smooth, solid; milk white, unchangeable, copious,
