 Plate x IX of this Report. 



IMLEl'S 1-10 cm. broad, firm, tx ming fragile, convex-plane, 



dull-red, variegated with yellowish, ochraceous or olivaceous 

 purplish hues. ;ii first darker, fading, pellicle adnate, dry, scarcely 

 separable and substriate on the margin, subglabrons, margin acute 

 and at first straight. FLESH whitish, staining slowly red then 

 black where wounded, becoming cinereous from age. GILLS nar- 

 rowly adnate, broader in front, close t<> subdistant, medium broad, 

 equal, rarely forked, white at first then pair rrcamif-nclmirrmis, in 

 tervenose. STEM o-7 cm. long, 1-2.5 cm. thick, subequal or tapering 

 down, spongy-stuffed, glabrous, even, while, becoming cinereous in 

 age, changing slowly to red then blackish whore bruised. 8P( >RES 

 globose, pale ochraceous, 7-10 micr. CYSTIDLA few and short. 

 subhymemum not differentiated. TASTE mild. ODOB none. 



Gregarious or scattered. On the ground in frondose woods. Ann 

 Arbor. July-August. Infrequent. 



Remarkable among the Subrigidae for the changes which the flesh 

 assumes on bruising. It approaches 7?. nigrescentipes I'k.. bu1 that 

 species is said to have a shining red cap and crowded white -ills. 

 and the stem turns blackish; n<> mention is made of any red 

 stains preceding the black and since the change is Blow it could 

 scarcely be overlooked. Our species has appeared from season t<> 

 season but never in abundance. It is a firm plant when fresh, be- 

 coming fragile only in age. If is apparently also related to B. 

 depallem Pr. but Maire says "nobody knows this, even in Sweden." 

 //. obscura "Rom. has a velvety pruinose pileus whose color is rather 

 uniform, and whose flesh is of a differenl consistency. 



Micro-chemical tests: G. (Gills and flesh turn bine., s V. (Gills 

 and flesh turn bluish very slowly.) F S. (Cystidia colored brown). 



As this report was ready for the press there appeared in print 

 the above name applied by Beardslee to a species from Asheville, 

 "X. C. which seems identical with ours.
