Polyporaceae 



have eaten it, and continue to do so. Yet Professor Peck (48th Rep., Boletus, 

 p. 202) reports a case brought to his notice of an entire family being 

 sickened by eating B. sensibilis. All recovered. It may, therefore, be 

 one of those species which, while disagreeing with some persons, can 

 be eaten by the majority. Clitocybe illudens, Lepiota Morgani and 

 others of the Agaricaceae are such species. 



B. bi'color Pk. two-color. (Plate CXVII, figs. I, 2, p. 424.) Pi- 

 leus convex, glabrous or merely pruinose-tomentose, dark-red, firm, be- 

 coming soft, paler and sometimes spotted or stained with yellow when 

 old. Flesh yellow, not at all or but slightly and slowly changing to 

 blue where wounded. Tubes nearly plane, adnate, bright-yellow, be- 

 coming ochraceous, slowly changing to blue where wounded, their 

 mouths small, angular or subrotund. Stem subequal, firm, solid, red, 

 generally yellow at the top,. Spores pale,- ochraceous-brown, 10 

 12.5x4-5/4. 



Pileus 2-4 in. broad. Stem 1-3 in. long, 4-6 lines thick. 



Woods and open places. New York, Peck; Wisconsin, Bundy. 



The color of this plant is somewhat variable. In the typical form the 

 pileus and stem are dark red, approaching Indian red, but when old the 

 color of the pileus fades and is often intermingled with yellow. The 

 surface sometimes cracks and becomes cracked in areas. From the 

 European B. Barlae this species is separated by its solid stem; from B. 

 versicolor by its small tube mouths and its red stem. Peck, Boleti of 

 the U. S. 



Plentiful at Mt. Gretna, Pa., July, August, September, 1898, in 

 mixed woods. Very variable in shape and color. Identified by Pro- 

 fessor Peck from painting and description. 



Fine eating, one of the very best. 



B. glabel'lllS Pk. smooth. PileilS fleshy, thick, broadly convex or 

 nearly plane, soft, dry, subglabrous, smoky-buff. Flesh white, both it 

 and the tubes changing to blue where wounded. Tubes nearly plane, 

 adnate, ochraceous, tinged with green, their mouths small, subrotund. 

 Stem subequal, glabrous, even, reddish toward the base, pallid above, 

 with a narrow reddish circumscribing zone or line at the top. Spores 

 oblong, brownish-ochraceous, tinged with green when fresh, 10-12. 5x4^. 



PileilS 3-5 in. broad. Stem 1-3 in. long, 5-10 lines thick.
