Possibly the oil globules to be seen in the spores of a 

 freshly cut Bahamia may for the moment be mistaken for 

 the parasitic spores. It can readily be shown that there 

 exists no connection between the two, as one has but to 

 place 'the material in a fluid denser than water, and the oil 

 globules will soon disappear from sight. 



The affinities of Sporofhaga cyanea are decidedly obscure 

 and will probably remain so until the earlier stages of the 

 development of its spore are noted. In the interval it may 

 be placed either amongst the Uredince or the Ustilaginece. 



The freshly cut surface of the host-plant shows a de- 

 cidedly blue tint, due to the presence of the parasite. 



Host-plant found at Auburn, Placer County, Calif,, April.
