Credosjiores. Sori amphigenous or on the steins, numerous, 

 scattered, sometimes confluent, minute, pulverulent, surrounded 

 lty the torn epidermis, cinnamon ; spores globose to ellipsoid, 

 echinulate, yellowish-brown, 21 — 27 //.; epispore moderately 

 thick, with two germ-pores. 



Teleutospores. Sori similar, but blackish-brown ; spores 

 ellipsoid, rarely obovate, rounded above and not thickened, 

 hardly constricted, generally rounded below, smooth or faintly 

 verruculose, brown, 27 — 38 x 19 — 25 /x; epispore thin; pedicels 

 hyaline, short, deciduous. 



On Cichorium Intybus. Rare. August — October. 



This species closely resembles Puccinia Hieracii, and there seem to 

 have been no cultures which give any information about its distinctness. 

 It is therefore separated merely on the ground of the difference of the 

 genus of the host ; see under P. Hieracii. 



Distribution : Europe ; introduced into Australia.
