Polyporaceae 



Boletus., ening and becoming thinner upward, even, variegated with yellow and 

 red, solid. Spores pale-olive, elongato-fusiform, 10 1 2x4/4. 



In woods, under oaks, etc. Pileus bronze-brown, sometimes with 

 purple shades. Often grows in dense clusters, and in this particular 

 differing from any other British species. Very good for eating. Massee. 



Haddonfield, N. J. Oak woods. August to September, 1894. Mt. 

 Gretna, Pa., 1898. Mcllvaine. 



Solitary. A handsome valuable species which appears to be rare in 

 the United States. Shade a beautiful bronze. Cap 3-4 in. across. A 

 dozen or more individuals were found and eaten. Excellent. 



B. frustulo'sus Pk. frusttihim, a small bit. Pileus thick, convex 

 or nearly plane, subglabrous, cracked in areas, white or whitish. Flesh 

 whitish. Tubes equal to or a little longer than the thickness of the 

 flesh of the pileus, depressed about the stem, whitish, becoming pale 

 brown. -Stem equal, solid, whitish, reticulated above. Spores 15- 

 17x5-6;*. 



Pileus 3-5 in. broad. Stem 1-2 in. long, 6-IO lines thick. 



Open grounds and clay banks. Ocean Springs, Mississippi and 

 Akron, Alabama. May and June. Underwood. 



The deeply cracked surface of the pileus is the most notable feature 

 of this species. This sometimes is seen even in quite young plants. 

 The cracked areas are quite unequal in size. The deep chinks with 

 sloping sides cause them to appear like frusta of polygonal pyramids. 

 In some specimens the reticulations of the stem extend nearly or quite 

 to its base, and make the place of the species ambiguous between the 

 Calopodes and Edules. Peck, Bull. Torrey Bot. Club, Vol. 24, No. 3. 



Mt. Gretna, Pa., September, 1898, on soil over red conglomerate 

 and on road-sides. Mcllvaine. 



The deep cracks in the cap readily distinguish this species. After 

 rains the caps are frequently slightly dished and widely cracked at 

 margin. The exposed flesh dries with a fine silky gloss. The caps 

 are excellent. The tubes and stem should be removed. 



B. cras'sipes Pk. thick-footed. (Plate CXVI, fig. 5, p. 420.) 

 Pileus convex or centrally depressed, firm, dry, velvety, brown tinged 

 with yellow, the wavy or lobed involute margin extending beyond the 

 tubes. Flesh lemon-yellow, unchangeable, taste sweet, odor like that
