THE RUSTS OF NOVA SCOTIA. — FRASER. 399 



excejDt a low papilla where the germ pore emerges, finely 

 punctate; pedicel hyaline, deciduous, shorter than spore. 



On Onopordon Acanthium L., Pictou, New Glasgow, 

 French River. 



Svdow in his Monograph describes two new species of rusts 

 on Onopordon, Puccinia Onopordi from Syria ;.nd Puccinia 

 Acanthi from Germany, the latter differing from the former in 

 having smaller teliospores. My collections have even larger 

 teliospores than P. Onopordi and are therefore placed under 

 that species. 



Puccinia Bardanae Cda. 

 & T. Pycnia and aecia unknown, possibly wanting. 



II. Uredinia amphigenous, scattered, rounded, pulverulent, 

 cinnamon. Uredospores globose, subglobose or ellipsoid, 

 echinulate, light brown, 26-30 by 22-27itt. 



III. Telia amphigenous mostly hypophyllous, scattered, 

 small, rounded pulverulent, blackish. Teliospores ellipsoid, 

 apex not thickened, slightly constricted at the septum; wall 

 dark bro\vn, finely verrucose, 22-27 by 30-42/x ; pedicel hyaline, 

 short. 



On leaves of Arctium Lappa L., Pictou. 



This species does not seem to have been previously reported 

 from Xorth America. Tt was collected in only one place in 

 the town of Pictou.

0. Pyimia not observed. 



1. Aecia probobly uot formed.
