I have seen no specimens of this species which is recorded 
from but one locality in our country. Thecharacter, “flesh 
sparingly changing to blue” is given on the authority of 
Reva ME; Berkeley, 
Boletus chrysenteron Fr. 
GOLDEN-FLESH BoLETus. RED-CRACKED BOLETUS 
Hym. Eur. p. 502. Syl. Fung. Vol. V1, p. 14 
Pileus convex or plane, soft, floccose-squamulose, often 
rimose areolate, brown or brick-red, flesh yellow, red beneath 
the cutzcle, often slightly changing to blue where wounded ; 
tubes subadnate, greenish-yellow, changing to blue where 
wounded , their mouths rather large, angular, unequal ; stem 
subequal, rigid, fibrous-striate, red or pale-yellow; spores 
fusiform, pale-brown, .00045 to .0005 in. long, .c0016 to .0002 
broad. 
Pileus 1 to 3 in. broad; stem 1 to 3 in. long, 3 to 6 lines 
thick.

The species is common and very variable. The color of 
the pileus may be yellowish-brown, reddish-brown, brick-red, 
tawny or olivaceous. The subcutaneous reddish tint and 
the reddish chinks of the rimose pileus are distinguishing 
features. Wounds of the tubes sometimes become blue 
then greenish. Authors disagree concerning the edible 
qualities of this Boletus. Stevenson gives it as edible, but 
Cordier and Gillet say that it is regarded with suspicion. In 
one strongly marked form the tubes are decidedly depressed 
around the stem, in another the flesh is whitish tinged with 
red. It may be doubted whether these are varieties or 
distinct species.
