THE RUSTS OF NOVA SCOTIA. FRASER 395 



The rust is not conspicuous but will doubtless be found 

 to be common and generally distributed. 



Puccinia Cichorii (DC.) Bell. 



0. Pycnia not observed. 



1. Aecia not known, probably not formed. 



II. Uredinia ampbigenous and caulicolous, scattered, 

 minute, chiefly round, pulverulent, cinnamon. Urediniospores 

 globose or subglobose, 22-27/* in diameter ; wall light brown, 

 echinulate. 



III. Telia mostly caulicolous, oval, blackish-brown. 

 Teliospores ellipsoid or ovate-ellipsoid, slightly or not con- 

 stricted at the septum, 21-28 by 30-46/u, rounded at the apex 

 and base; wall uniform, smooth, brown; pedicel hyaline, 

 delicate, deciduous. 



On Cichorium Intybus L., Durham, August 16, 1910. 



This species does not seem to be common, as only one 

 collection was made. 



Puccinia obtegens (L.) Tul. 



Puccinia suaveolens Lk. 



0. Pycnia hycophyllous, at length covering the whole 

 surface of the leaf 



I; Aecia not formed. 



II. Uredinia hypophyllous, at length amphigenous, 

 scattered on upper, crowded on lower surface of leaf, pul- 

 verulent, dark brown. Urediniospores globose or subglobose, 

 25-30/*; wall light brown, echinulate, pores three. 



III. Telia similar to the uredinia. . Teliospores ellipsoid 

 or ovate-ellipsoid, 18-22 by 32-35/x, rounded at both ends or 

 base, slightly narrowed, not or slightly constricted at the 

 septum ; wall uniform, brown, slightly verrucose ; pedicel
