 Notes. 



C. pilularia, C. xanthopila, C. physcopodia and C. tagetes 

 were described from specimens sent to Montagne by Sullivant 

 and have not been recognized since. 



Morgan's description of C. estensis is rather meager. It is 

 probably a form of C. dryophila or perhaps is identical with C. 

 strictipes. 



The plants referred by Hard (p. 108) to C. ingrata 

 Schum. should probably be considered a form of C. confluens. 

 According to Berkeley (Outlines of British Fungology, p. 117), 

 the principal diiTerence between the two species is that in the 

 former the lamellae more nearly approach the stipe. 



Some writers believe that C. tenuipes and C. amabilipes are 

 identical. Schweinitz described the former as having a stipe 

 15-30 cm. long, pileus depressed and subumbonate, plants grow- 

 ing among decaying leaves. The Ohio plants grow on decayed 

 wood, the pileus is convex-expanded, and the stipe is variable in 

 length, but seldom more than 8-10 cm. long. Peck's description 

 of C. amabilipes fits our plants more closely, and unless we as- 

 sume that Schweinitz had very exceptional specimens, they 

 should be known by Peck's name. Lloyd says the pileus is 

 slightly viscid, but we have never found it so. (Myc. Notes
