426 THE RUSTS OF NOVA SCOTIA. FRASER. 



II. Uredinia hypophyllous, oblong. Urediniospores ovate, 

 echinulate, 14-17 by 17-22/*; wall thin, brownish. 



III. Telia hypophyllous, oblong or linear, soon naked, 

 surrounded by the ruptured epidermis, dark brown or blackish. 

 Teliospores oblong or oblong-clavate, apex mostly rounded, 

 much thickened, 16-21 by 37-60^; pedicel tinted, shorter than 

 or equalling the spore. 



Puccinia and aecia on Aster acuminatus Michx. and other 

 Aster species, Pictou. 



Uredinia and telia on Carex trisperma 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 Carices belong to 

 this species. That on Carex canescens Var. disjuncta Fernald 

 is probably included here. 



Puccinia Caricis=Solidaginis Arthur. 



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

 species of Solidago, Pictou. 



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

 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.

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