The shape of the young and old pileus of ihis variety is well 

 represented in Cooke's figure of R. decolorans, Plate 1079. The 

 color of the pilens is. however, ruber-red (Sacc. colors) and persist 

 ent, changing only in age or on drying as a result of the cinerescenl 

 flesh. The pellicle is ruinate, scarcely separable excepl on the mar 

 gin, vanishing on the disk and sometimes ochraceus-spotted where 

 the pellicle lias disappeared. It is firm and the margin is nol 

 striate or very slightly so in age. These characters ally it to the 

 Rigidae. it is slightly viscid. FLESH is firm, while, tinged ashy 

 in age, becoming dark cinereous on the sU m where bruised. The
