to blue when broken, A shade of 3'ellow sometimes appears beneath 

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

 blackish, glabrous and shining. 



h. Flesh unchanged. 



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

 villous-tomeutose, 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 about 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. AURiPORDS, Peck. — Pileus broadly convex, dry, most minutel}- 

 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 gi-een- 

 'sh tinge in the white flesh next the pores in the section; the stipe is 

 red above and yellow below. » 



C. Tubules yellow, the pores red. 



7. B. MAGNispoRus, Frost. — Pileus firm, pulvinate, tomentose, golden 

 yellow. Stipe slender, long, 3'ellow above and red below. Tubules 

 scared}' adnate, greenish-yellow; pores minute, even, cinnabar-red* 

 Spores .016— .017X.006 mm. 



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

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

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



8. B. VERMicuLoscs, Pcck. — 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.
