I'lLI'l's 8 i ~» cm. brond, . firm, convex then depressed, with 



dull colors, dark reddish-purple, sordid red, sometimes mixed with 

 other shinies, the reddish color predominating, with somewhat 

 separable pellicle, glabrous, somewhal viscid in wet weather, soon 

 dry, pritinosi • ftubgranulosr, in even or somi ort- 



striate in age. FLESH white, thick. <;!U,s orhra the 



beginning, deeper ochraceous to tan-colored when mature, rather 

 broad, thick, subdistant, broader in front, rounded adnexed, <>r 

 tqval length. STEM 7-10 cm. long, 3-4 cm. thick, very firm, stout, 

 solid, tinged red or entirely white, subequal or ventricose, almosl 

 even. SPORES ochraceous-yellow to alutaceous, Bubglobose, 9-11 

 inter. TASTE mild. ODOR none or pleasant. 



Usually solitary and rather late. Oak and maple woods of south- 

 ern Michigan. Nol very common. August and September. 



As limited above, m> bright or shining red forms are admitted 

 from our territory. This species and B. mtegra have been the re 

 ceptacle for a good many reddish species with ochraceous gills, and 

 even experienced mycologists cannol agree on their identification. 

 I have kept this name for a large, solitary, often Late plain, with 

 firm or hard consistency and dull, dark red and purplish cap, with 

 truly ochraceous gills and spores. B. Integra has cream-colored or 

 at least paler spores and is more fragile and often grows in troops. 

 The descriptions <>\' this and !'. orhrophglla ran close together. 

 Cooke's illustration of /.'. alutacea fits our plants well. 



FRAOILES, Pileus thin, fragile, the viscid pellicle continuous 

 and quite separable, margin connivent, nol incurved when young, 

 usually strongly striate. The gills are of equal length, broader 

 anteriorly, aarrowed behind. 



Section I. Taste acrid. Spores white in mass.
