 Plate XIV of this Report. 



PILEUS 5-12 cm. broad, dry, convex-depressed, margin ;it tii^i 

 incurved, glabrous, even, dingy whiU becoming smoky with age. 

 FLESH whitish, compact, becoming blackish-brown >>r bluish-black 

 when bruised, without first turning reddish. GILLS adnate i" -ni»- 

 decurrent, rather narrow, close, long and shori alternating, white 

 becoming blackish in <i</<-. fe\* forked. STEM 3-5 cm. long, l - cm. 

 thick, short, solid, rigid, equal, whitish becoming black when 

 handled. SPOBES globose, 7-8 micr., whit.- in mass. TASTE mild 

 or tardily and slightly acrid. <>I><)R none 



Gregarious or solitary. <>u the ground in the hemlock regions of 

 the north, rarely in southern Michigan. July-August. Infrequent. 



This differs from the European /.'. albonigra (Kromb.) in its dry 

 pileus. A species lias been named by reck with viscid cap, viz.. 

 /,'. sub sordida) this is probably identical with /.'. albonigra. our 

 plant lias n dry pileus and differs from /«'. ui<iii<-<ins and R. densi- 

 folia in the lack of the change to red immediately after bruising. 

 Tn specimens found near Ann Arbor the gills of tin- young plants 

 were easily separable from the trama of the pileus; whether this 

 is a constant character I cannot say. Peck found the -am.- to be 

 true in specimens of R. densifolia. The stems are said To be 

 often infested with jjnibs.
