Boletus chrysenteron albocarneus n. var. White Flesh Boletus. 

 Pileus fleshy, convex above, dry, subglabrous, varying from brick red to 

 bay red. Flesh white, sometimes tinged with red near the surface; 

 tubes rather long, adnate or slightly depressed around the stem, green- 

 ish yellow, their mouths small, subrotund. Stem equal or nearly so, 

 solid, subglabrous, colored like or a little paler than the pileus, white 

 within. 



The white flesh boletus is quite common in the Adirondack forests 

 and quite constant in its characters. I have not seen it with yellow 

 flesh, though in other respects it agrees very well with the description of 

 B. chrysenteron. The cap is not often cracked, but, when it is, the 

 cracks are sometimes red, sometimes yellowish, though the flesh is con- 

 stantly white except just beneath the cuticle, where it is sometimes red- 

 dish. The tubes are long and greenish yellow. They are at first nearly 

 plane in the mass, but with the expansion of the cap the mass often be- 

 comes ventricose. The mouths of the tubes are small and nearly 

 round. Wounds or bruises of the mass become bluish or greenish blue. 

 The stem is firm, solid and colored like the cap, though it is sometimes 

 a little paler. 



The Cap is 1-2.5 inches broad; the Stem 1-2 inches long, 2-4 lines 

 thick. The trial specimens were fried in butter and found to be harm- 

 less, palatable and digestible. Peck, 54th Rep. N. Y. State Bot.
