Polyporaceae 

 Boletus. B. parasiticus is edible, but it is not of agreeable flavor. 



B. dictyocepll'alus Pk. reticulate. Pileus convex, glabrous, reticu- 

 late with brown lines beneatJi the thin separable cuticle , brownish-orange, 

 darker in the center and there tinged with pink. Flesh white, un- 

 changeable. Tubes nearly plane, slightly depressed around the stem, 

 grayish-yellow, becoming brown where bruised. Stem equal or slightly 

 tapering at the top, solid, rimose, dotted with scales, lemon-yellow, 

 darker toward the base. Spores 15 2Ox6/u.. 



Pileus 2.5 in. broad. Stem 3-4 in. long, 5-6 lines thick. 



Mixed woods. North Carolina. C. J. Curtis. 



The description here given has been derived from a single dried speci- 

 men and from the notes kindly sent by Mr. Curtis. The species is 

 apparently well marked and very distinct by the peculiar reticulations of 

 the pileus. Peck, Boleti of the U. S. 



B. subgla'bripes Pk. rather smooth. Pileus convex or nearly 

 plane, glabrous, reddish inclining to chestnut color. Flesh white, un- 

 changeable. Tubes adnate, nearly plane in the mass, pale yellow, be- 

 coming convex and darker or greenish-yellow with age, the mouths 

 small, subrotund. Stem equal, solid, scurfy, pale yellow. Spores 

 oblong-fusiform, 12.5-15x4-5^. 



The smoothish-stemmed Boletus is well marked by its cylindric mi- 

 nutely scurfy stem which is colored like the tubes. Its cap is smooth 

 and nearly always some shade of red or L 'Specimens occur occa- 

 sionally in which it approaches grayish-bro\,,i or ,y oc, 1-brown . The 

 flesh is white and unchangeable when cut or bro! \, 



The tubes at first have a nearly plane surface, but this becomes some- 

 what convex with age, and slightly depressed around the stem. The 

 tube mouths are small and nearly round. The color of the tubes is at 

 first a beautiful pale yellow, but it becomes darker or slightly greenish- 

 yellow with age. 



The stem is colored very nearly like the tubes, but sometimes it has 

 a slight reddish tint toward the base. Its peculiar feature consists of 

 the minute, branny particles upon it. They are so small and pale that 

 they are easily overlooked. 



There is a variety in which the cap is corrugated or irregularly pitted 

 and wrinkled. Its name is Boletus subglabripes corrugis Pk.
