Notes. 



T . porrigens A'iv., listed by Alorgan (Jour. Alyc. 13:6) is 

 ]jr()ljal;ly to be considered a wbite form of L. procera. 



L. lutea Bolt., listed by Morgan (Jour. Afyc. 13:4). is 

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



L. rufipes ]\Iorg. Jour. jN'Iyc. 12:156, is probably not specifi- 

 cally distinct from L. mesomorpba Bull. 



Tbe 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. 

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

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

 measurements for both species. 



Several writers state that L. americana is L. badhami B. &:
