In woods. A rare species that I have not seen, neither 

 can I find any specimens in herbaria, hence cannot give 

 form or size of spores. Flesh of pileus ^ in. or more thick, 

 tinged yellow, becoming blue when cut ; this colour soon 

 fades, leaving the flesh white. Stem l|-2 in. long, 1-1^ in.

 margin when young, glabrous pileus, and reddish, vaguely 

 reticulated obese stem.
