to blue when broken. A shade of yellow sometimes appears beneath 

 the brown of the pileus, and as the plants grow old, the pileus becomes 

 blackish, glabrous and shining. 



b. Flesh unchanged. 



5. B. subtomentoscs, Linn. — -Pileus pulvinate-expanded, soft, dry, 

 villous-tomentose, somewhat olivaceous, concolorous beneath the cu- 

 ticle. Stipe stout, somewhat costate sulcate, under a lens punctate- 

 scabrous. Tubules adnate; the pores large, angular, yellow. Spores 

 olive, fusiform, .012— .013X.005 mm. 



In woods a'bout old stumps and logs, in summer and autumn; com- 

 mon. Pileus 1-^-3 in. broad, stipe 2-3 in. long, and an inch thick. 

 In size and habit this species very much resembles B. chrysenteron; 

 when the pileus is rimose, the cracks are of the same color as the flesh 

 or the cuticle, and not red; the flesh is white or pallid, growing yellow 

 by exposure. 



6. B. auriporus, Peck. — Pileus broadly convex, dry, most minutely 

 tomentose, grayish-brown, sometimes tinged with red. Stipe equal, firm, 

 solid, smooth. Tubules plain, or nearly so, adnate or somewhat decur- 

 rent; the pores medium, round, bright golden yellow. Spores olive, 

 fusiform, .012X.005 mm. Flesh white, unchangeable. 



In woods in summer; scarce. Pileus 2 : 3 in. broad, stipe 2-4 in. long, 

 and an inch thick. The plant I have so referred has a slight green- 

 ish tinge in the white flesh next the pores in the section; the stipe is 

 red above and yellow below. 



O. Tubules yellow, the pores red. 



7. B. mag-nisporus, Frost. — Pileus firm, pulvinate, tomentose, golden 

 yellow. Stipe slender, long, } r ellow above and red below. Tubules 

 scarcely adnate, greenish-3 7 ellow; pores minute, even cinnabar-red- 

 Spores .016— .017X.006 mm. 



In woods, in summer; rare. Pileus 2^ 3^ in. broad, stipe 4-5 in. 

 long. The tomentum of the pileus is sometimes brownish-yellow; the 

 flesh is greenish -yellow, changing to blue when cut or broken. 



8. B. vermiculosus, Peck. — Pileus broadly convex, dry, smooth, or 

 most minutely tomentose, grayish-brown tinged with red. Stipe equal, 

 solid, smooth, paler than the pileus. Tubules plane or slightly con- 

 vex, free; the pores small, round, yellow, brownish-orange, becom- 

 ing almost black. Spores fusiform .011 — .014X. 004mm. Flesh white, 

 changing to blue.
