Notes. 



L. porrigens Viv., listed by Morgan (Jour. Islyc. 13:6) is 

 probably to be considered a white form of L. procera. 



I-. lutea Bolt., listed by Morgan (Jour. Myc. 13:4), is 

 usually regarded as a yellow form of L. cepaestipes. 



L. rufipes Morg. Jour. Myc. 12:156, is probably not specifi- 

 cally distinct from L. mesomorpha Bull. 



The occurrence of L. farinosa Peck in Ohio is doubtful. 

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

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

 Myc. 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 L. badhami B. & 

 P)r. of Europe.
