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 .V in. or more thick, 

 tinged yellow, becoming blue when cut ; this colour soon 

 fades, leaving the flesh white. Stem li-2 in. long, 1-li- in.

 margin when young, glabrous pileus, and reddish, vaguely 

 reticulated obese stem.

 dark-brown or umber-brown, often wavy, slightly tomentose, 

 margin incurved; flesh very thick, yellowish, sometimes 

 unchangeable, at others changing to green or blue, and finally 

 becoming reddish when broken ; tul)es shortened round the 

 stem and almost free, }j in. or more long, openings small, 

 roundish, yellow then greenish ; stem at first stout, ovate, 

 usually tapering at the base, then lengthening and becoming 

 thinner upwards, even, variegated with yellow and red, 

 solid : spores pale olive, elongato-fusiform, 10-12 X 4 /x.
