Cultures of some heteroecious rusts, W. P. Eraser (Mycologia, S (1911), 

 No. 2, pp. 67-7-'/). — Successful cultures are reported as follows: Teleutospores 

 of Melampsoropsis cassandrw from C1iam<Edap1ine calyculata produced secidia of 

 Pei-idermium consimile on Picea rubra ; teleutospores of M. abietina from Ledum 

 grcenlandicum produced secidia of Peridermium abietiniim on Picea rubra; teleu- 

 tospores of M. ledicola from Ledum sp. produced secidia of Peridermium 

 decoJorans on Picea canadensis; teleutospores of Uromyces peckianus from 

 Disiichlis spicata produced secidia on Atriplex patula hastata and Chenopodium 

 album. 



In addition to the cultures noted, the alternate stages of these rusts were 

 found constantly associated on their corresponding hosts in the open fields and 

 woods. Also, M. pyrolxe was found associated with PeridermAum, cwiorumr 

 picece, the uredo and teleutospore stages on Pyrola americana and P. elliptica, 

 and the secidial sta%e on the young pistillate cones of Picea mariana. The 

 aecidial stage of Calyptospora columnaris is reported as common on young plants 

 of Abies balsamea.
