DESCRIPTIONS OF FUNGI. 123 



Brown. 



BOLETUS CASTANEUS = chestnut. 

 The Chestnut Boletus. 



Cap a chestnut color, brown or reddish 

 brown, \\ to 3 inches broad, convex, nearly 

 plane or depressed, firm, even, dry, minutely 

 velvety (tomentose), flesh white. Tubes free, 

 short, small, white, becoming yellow. Stem 

 1 to 2J inches long, 3 to 5 lines thick, equal 

 or tapering upward, even, stuffed or hollow, 

 colored like the cap. This is one of the pretti- 

 est of the Boleti. The bright chestnut color 

 of the pileus forms a contrast with the white 

 tubes, and makes it striking in appearance. 

 We found it on several occasions, as it is com- 

 mon in woods. There are differences of opin- 

 ion in regard to its being edible. 



BOLETUS CHRYSENTERON = golden. 

 The Golden Flesh Boletus. 



Gap dark brown or reddish-brown, 1 to 3 

 inches broad, convex or plane, soft, covered with 

 woolly scales, sometimes marked with lines, 

 flesh yellow, red beneath the cuticle, often 

 slowly changing to blue when wounded, mouths 

 large, angular, unequal. Stem 1 to 3 inches
