Melampsoropsis ledicola (Peck) Arthur 



L'pon the occasion of a visit to "Agate bog " near Cohasset on 

 Fourth lake, northern Herkimer county on June 27, 191 7, there 

 was observed a great abundance of this rust upon the leaves of 

 Ledum groenlandicum. W. P. Fraser (]\Iycologia, 3 .yo. 

 191 1 ; 4:177. 1912) has connected by means of cultural experiments, 

 this rust with Periderm ium decolorans Peck. x\ccord- 

 ingly another visit was made to this bog on August 8.h, and a 

 corresponding abundance of the Peridermium upon P i c e a 

 m a r i a n a was observed. The absence of any species of Peri- 

 dermium upon Abies or Tsuga in the immediate vicinity of this 

 bog seems to corroborate Fraser's results. 



The rust upon Ledum has been collected by Doctor Peck in 

 Bergen swamp, Genesee county; Lake Pleasant, Hamilton county; 

 Sandlake, Rensselaer county, and on Mount Marcy, Essex county. 

 The Peridermium. upon Picea mariana has been collected 

 by Doctor Peck at Sandlake, Mount Colvin, North Elba and 

 Elizabethtown, and by H. D. House at Featherstone lake, Schenec- 

 tady county.
