426 THE RUSTS OF NOVA SCOTIA. ^FRASEH. 



II. Uredinia hypophylloiis, oblong. Urediniospores ovate^ 

 ecbiniilate, 14-17 by lT-22/x; wall thin, brownish. 



III. Telia hypo])byllons, oblong or linear, soon naked» 

 surrounded by the ruptured epidermis, dark brown or Ijlaekisli. 

 Teliospores oblong or oblong-clavate, apex mostly rr-undod, 

 much thickened, 16-21 by 37-60^; ])edicel tinted, shorter than 

 or equalling the spore. 



Puccinia and aecia on Aster acumnmtus ^lichx. and other 

 Aster species, Pictou. 



Uredinia and telia on Carex trhperma Dewy, and probably 

 on other Carex species, Pictou. 



The writer established by cultures that the Puccinia on 

 Carex trisperma has aecia on Aster acuminatus. It is prob- 

 able that a number of other collections on Car ices belong to 

 this species. That on Carex canescens Var. cUsjuucta Pernald 

 is probably included here. 



Puccinia Caricis=SoIidaginis Arthur. 



& I. On Solidago graminifoUa (L.) Salisb. and other 

 species of Solidago, Pictou. 



II. & III. Uredinia and telia on Carex scoparia Schk. 

 and C. stipata Muhl., Pictou, 



There does not seem to be any marked morphological 

 differences between the forms of this species and Puccinia 

 Caricis-Asteris so that a description is not given. 



Cultures by the writer established the connection of the 

 above forms for this region. (See Mycologia 4:181. 1912). 

 It is probable that other collections of Puccinia on sedges in 

 this vicinity belong to this species. 



Puccinia caricina DC. 



On Carex Deweyana Schwein., C. pauper cula Michx., C. 

 stellulata Good., C. stellulata Var. cephalaniha (Bailey)
