Among grass in damp places. 



Agreeing with E. ocliroleuca in the white stem becoming 

 grey, but differing in the clear deep chrome-yellow pileus, 

 and in the white gills becoming pale lemon-yellow, then 

 somewhat ochraceous. 



The smooth, even, rigid pileus, at length cinereous stem, 

 and coloured gills are its distinguishing features. (Grove.)

A very showy species ; taste very acrid ; very hard and 

 rigid ; very distinct from all other species of this section in 

 the even, polished pileus without a distinct pellicle, the 

 somewhat grumous flesh, and exceedingly acrid taste.
