Notes. 



I. auricoma Batsch, listed by Lea. is regarded by Fries as 

 a variety of I. descissa. Morgan, who worked in the same region 

 as Lea. did not collect it. Tt is possible that Lea's plants were 

 incorrectly determined. The species is omitted from the list. 



It is worthy of note here that Peck enumerates 39 species 

 for the state of New York. Of the 9 species reported from Ohio 

 only 5 occur in Peck's list. It is remarkable that such a dis- 

 parity should occur in states no more widely separated. It is 

 probable, however, that furtlier study of Ohio plants will add 

 a number of species to the Ohio list.
