246 BROOKLYN BOTANIC GARDEN MEMOIRS 



made for overwintered telia on Cyperaceous hosts associated with the 

 Senecio and the only rust found was on very much weathered leaves 

 which have been determined by comparison of the microscopic struc- 

 ture as above indicated. 



Tranzschel (Beitr. Biol. Ured. Ill: 4. 1907), working in Russia, 

 was the first to culture this species. He used telial material on 

 Eriophonim angnstijoliiim to successfully infect Ligularia sihirica and 

 Senecio paluster. 



In America, Arthur (Mycol. 8: 131. 1916), using aecial material 

 from New York on Senecio aureus, obtained successful infection result- 

 ing in uredinia and telia on E. viridi-carinatuni. 



102. Puccinia Eriophyllii sp. nov. 



O. and I. Pycnia and aecia unknown. 



II. Uredinia amphigenous and caulicolous, scattered, small, 

 roundish, 0.3-0.6 mm. across, early naked, pulverulent, pulvinate, 

 chestnut brown, surrounding epidermis not conspicuous; uredinio- 

 spores globoid, obovoid or oblong, 21-27 by 26-29 M. wall chestnut 

 brown, 2-3 n thick, moderately and finely echinulate, pores 2, approxi- 

 mately equatorial. 



III. Telia amphigenous, scattered, small, round, 0.3-0.6 mm. 

 across, early naked, compact, pulvinate, blackish brown, ruptured 

 epidermis not conspicuous; teliospores ellipsoid to oblong, 18-21 by 

 26-30 n, apex and base rounded, not constricted, wall chestnut brown, 

 2-2.5 M thick, uniform, minutely and obscurely verrucose; pedicel 

 colorless, deciduous.

Distinguished from other species of Puccinia on related hosts by 

 the very small teliospores.
