Polyporacese 



Boletus. B. rimosel'lus Pk. cracked. PileilS broadly convex, flat or irregu- 

 lar, glabrous, tesscllately cracked, dark-brown. Flesh whitish. Tubes 

 adnate or sinuately decurrent, somewhat depressed around the stem, 

 pale-yellow, becoming darker or brownish with age. Stem tapering up- 

 ward, broadly reticulated with brown veins, yellowish-white. Spores 

 fusiform , 1 5 - 1 7 . 5 x 5 -6p, . 



PileilS 3-5 in. broad. Stem 3-4 in. long, 6-9 lines thick. 



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



I have described this species from the notes and a single dried speci- 

 men sent me by Mr. Curtis. More extended observation may require 

 some modification of the description. The color of the spores is de- 

 scribed as brown. They are remarkable for their size. Peck, Boleti 

 of the U. S. 



B. modes'tus Pk. modest. Pileus convex or nearly plane, often 

 irregular, firm, dry, very minutely tomentose, yellowish-brown. Flesh 

 gray or pinkish-gray. Tubes nearly plane, adnate or subdecurrent, 

 the mouths angular, pale-ochraceous. Stem equal, reticulated, brown. 

 Spores elliptical, IOXS/A. 



Pileus 2-3 in. broad. Stem 1-2 in. long, 2-4 lines thick. 



Grassy ground in thin woods. New York, Peck. 



Miss Banning finds in Maryland what appears to be a form of this 

 species in which the part of the hymenium near the stem consists of 

 lamellae, the rest of tubes. The species needs further investigation.

B. Cur'tisii Berk. after Dr. Curtis. Pileus hemispherical or con- 

 vex, viscose, golden-yellow. Tubes depressed around the stem, nearly 

 free, their mouths umber, at length tawny. Stem slender, attenuated 

 upward, polished, reticulated, straw-colored. Spores ferruginous, sub- 

 elliptical, slightly attenuated at each end. 



PileilS i in. or more broad. Stem 2 in. long, 2-3 lines thick. 



Pine woods. North and South Carolina, Curtis. 



In the original description the stem of this species is said to be hol- 

 low. Peck, Boleti of the U. S. 



B. gri'seuS Frost gray. Pileus broadly convex, firm, dry, sub- 

 glabrous, gray or grayish-black. Flesh whitish or gray. Tubes adnate
