Polyporaceae 



Boletus, ish-brown, but it may be reddish-brown or taTvny-red. When it cracks 

 the chinks become yellow. The species, as I understand it, may be 

 distinguished from its near relative, B. chrysenteron, by its paler flesh, 

 the clearer yellow tubes not changing to blue where wounded, and by 

 the chinks of the pileus becoming yellow. The species is recorded 

 edible by Cordier, Curtis and Palmer. Gillet says it is only medium in 

 quality. Peck, Boleti of the U. S. 



Found and eaten in West Virginia, North Carolina, New Jersey, Penn- 

 sylvania. Specimens received from Indiana, Minnesota, Alabama. 

 I have not seen any change of color in flesh or tubes. It is common 

 in Woodland Cemetery and Fairmount Park, Philadelphia. If the 

 tubes are not removed the dish is slimy. The B. chrysenteron also 

 makes such a dish when stewed, but fried, and well done, both species 

 are decidedly good. 



B. CSespito'sus Pk. cespitose. Pileus broadly convex or nearly 

 plane, sometimes slightly concave by the elevation of the margin, even, 

 brown or blackish-brown, the margin often a little paler or reddish- 

 brown. Flesh slightly tinged with red. Tubes adnate or slightly de- 

 current, yellow, their mouths rather large, angular, concolorous. Stem 

 short, even, solid, glabrous, tapering upward, brown or reddish-brown. 

 Spores oblong-elliptic, lOft long, 5/* broad. 

 Pileus 1-2.5 cm - broad. Stem 2-2.5 cm. long, 4-6 mm. thick. 



Cespitose. Virginia. August. R. S. Phifer. 



A small species growing in tufts and referable to the tribe Subtomen- 

 tosi. The tubes retain their bright yellow color in the dried specimens.
