REMAP KS. The yellow rust, as this fungus is now generally known, 
occurs more frequently on wheat than on barley in several parts of Japan. 
This species can easily be distinguished macroscopically from other rust 
fungi on cereals by the yellowish discolored streaks of the uredosori on the 
leaves and also by the streak-dotted arrangement of the teleutosori on the 
sheath. 
This species was at first included with other species in Puccinia rubigo- 
vera DC. (P. striceformis West., P. straminis Fuck.). In 1894, ERIKSSON 
and Henning (i) divided Puccinia rubigo-vcra into two species, viz., 
P. glumarum (Schmidt.j and P. dispersa by their morphological characters. 
In 1899, ERIKSSON (4) divided old P. rubigo-vcra still further into the 
following eight species : — 
1. Puccinia glumarum (Schmidt.) Eriks, et Henn. 
The yellow rust (^Ecidium unkown). 
2. P. dispersa Eriks, (not Eriks. $t Henn.) 
The brown rust of rye (HLcidium on Anchusa). 
3. P. triticina Eriks. 
The brown rust of wheat (^Ecidium unknown). 
4. P. Symphyti-Bromorum Müll. ( = P. bromina Eriks.) 
The brown rust of bromes (^Ecidium on Symphytum). 
5. P. agropyrina Eriks. 
On Triticum repens (zEcidium unknown). 
6. P. holcina Eriks. 
On Holcus lanatus, H. mollis (yEcidium unknown).
