Distinguished by the dingy yellow pileus, broad white 

 gUls ronnded behind, and the grey stem. The centre of the 

 pilens is sometimes rather scurfy, owing to the breaking np 

 of the cuticle. 



B. granulosa differs in the stem not becoming grey ; gills 

 narrowed behind, and in the numerous, slightly projecting, 

 pointed cystidia. £. claroflata differs in the chrome-yellow 

 pileus, and in the white gills becoming pale le.uon-yellow, 

 then somewhat ochraceous. 



Structure and size, also in the acrid taste, asrreeing with 

 M. emetiea; differs distinctly in the stem being slightly 

 reticulately rugulose, and white then becoming greyisli ; 

 pellicle of pileus adnate, margin persistently even for a long 

 time, gills rounded behind, becoming pallid ; colour of 

 iiileus constantly yellow, becoming pale. Inodorous like 

 S. emetiea. (Fries.) 



Russxila granulosa. Cooke. 



Acrid. Pileus 2— 3J in. across, flesh rather thick, firm, 

 white ; convex then expanded, becoming depressed or even 

 infundibuliform, viscid at first, ochraceous, disc darker and 

 becoming broken up into minute granules, owing to the 

 cracking of the cuticle, margin even or faintly striate when 

 old; gills nearly free, narrowed behind, raiher crowded, 

 equal, rarely forked, white; stem 2-3 in. long, nearly or 

 quite equal, minutely granular or mealy throughout, 

 granules snow-white at the apex, brownish below, intemHlly 

 w^hite, spongy ; spores rough, subglobose, white, apiculate, 

 11-12 /i; cystidia pointed, only slightly projecting.
