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. III: 4. 1907), working in Russia, 
was the first to culture this species. He used telial material on 
Eriophorum angustifolium to successfully infect Ligularia sibirica 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-carinatum. 
102. Puccinia Eriophyllii sp. nov. 
O.and I. Pyenia 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 u, wall chestnut 
brown, 2-3 » thick, moderately and finely echinulate, pores 2, approxi- 
mately equatorial. 
Ill. 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 wu, apex and base rounded, not constricted, wall chestnut brown, 
2-2.5 w thick, uniform, minutely and obscurely verrucose; pedicel 
colorless, deciduous.
