differs in the stem "being cartilaginous and not fibrous 

 externally. Clitocybe 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 THE SPECIES. 



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