 Notes. 



C. pilularia, C. xantbopila, C. pbyscopodia and C. tagetes 

 were described from specimens sent to Montague by .'^ullivant 

 and bave 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 

 Sebum, should probably be considered a form of C. confluens. 

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

 the principal difference 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. Sclnveinitz described the former as having a stipe 

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

 ing among decaying leaves. The C)bio ])lants grow on deca\ed 

 wood, the pileus is convex-expanded, and the stipe is varial)lc in 

 length, but seldom more than S-io 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 l)e known by Peck's name. IJoyd says the pileus is 

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