differs in the stem being cartilaginous and not fibrous 

 externally. Clitocyhe differs in the gills never being sinuate, 

 but gradually narrowed benind ; pileus often umbilicate, &c. 

 In some species the gills separate readily from the pileus, 

 as in Paxillus, the latter, however, is distinct in the strongly 

 incurved margin of the pileus, and the anastomosing gills. 



ANALYSIS OF TEE SPECIES. 



Series A. Pileus viscid, fibrillose, scaly, or downy ; not 

 hygrophanous ; stem fibrillose from the remains of the 

 adnate universal veil. 



I. LiMACIXA.

 margin almost naked. 



* Gills not discoloured, and not becoming rufescent. 



** Gills discoloured, usually spotted with reddish-brown. 



II. Genuina. 



Pellicle of pileus never viscid, but torn into floccose or 

 fibrillose squamules ; flesh of pileus soft, not hygrophanous, 

 margin involute and somewhat downy at first. Not to be 

 confounded with those species that have the pileus fibrillose 

 from the remains of the veil. 



* Gills unchangeable, not becoming spotted with rufous 

 or black. 



** Gills becoming tinged with rufous or greyish ; edge 

 usually at length spotted with rufous or black. 



III. ElGIDA. 



Pellicle of the pileus rigid, granulated or broken up into

 scaly, not torn into fibrils. Pileus rigid, hard when the
