This differs from /.. piperatua in the velvet} tomentoee pileuj and 

 rather distant gills. /.. deceptions has a thick, cottony tomentum on 

 the Involute margin, bul is almost glabrous elsewhere. Sometimes 

 the milk of /.. vellerius seems to !><' lacking, when ii might be d 

 taken for R/ussula delica: the latter, however, lacks the tomentositv 

 of ilit* pileus as n rule, and often has a greenish tinge «>n the apex 

 of the Sinn and the edge of the gills. Its edibilty Is questioned, 

 i. in Mcllvaine ate it for years. Others also consider ii edible since 

 ir loses its acridity when cooked. Without doubt it can i»- eaten 

 i>\ sum,., inn like Lepiota morgani, causes bad effects in others. ] 

 nature of its harmful principle should be investigated.
