Notes. 



L. porrigens \ iv., listed by Morgan (Jour. .M\c. 13:6) is 

 ])ri)l)aldy to be considered a wbite form of L. procera. 



T.. lutea I'olt.. listed by Morgan (jour. Myc. 13:41. is 

 usuall}' regarded as a yellow form of L. cepaestipes. 



I., rufipes Morg. Jour. Myc. 12:156, is probably nd s])ecifi- 

 cally distinct from L. mesomorpha PjuII. 



Tbe occurrence of L. farinosa Peck in Ohio i> doubtful. 

 Peck separated it from L. cepaestipes on account of the even 

 margin and the larger spores (Report 43, p. 35), Morgan (Jour. 

 M}c. 13:1. 3) in reporting the former, says that the chief dif- 

 ference is in the color of the pileus. He gives the same spore 

 measurements for both species. 



Several writers state that L. americana is P. badhami P. & 

 P>r. of Europe.
