I. INTRODUCTORY STATEMENT 



The study of the Uredinales of California began with the pioneer 

 work of Dr. H. W. Harkness and Justian P. Moore, who in 1880 

 published a Catalogue of Pacific Coast Fungi, which enumerates fifty- 

 five species belonging to this group. Unfortunately this list does not 

 give the specific names of a large number of the host plants referred 

 to and also the localities are often very indefinite, which makes it diffi- 

 cult to correlate this list with the work of subsequent collectors. Some- 

 what later Dr. Harkness, either in conjunction with M. C. Cooke and 

 J. B. Ellis, or independently, published in Grevillea and in the Bulle- 

 tin of the California Academy of Sciences a number of new species 

 including many Uredinales. The extensive collections of Pacific Coast 

 fungi which Dr. Harkness had presented to the California Academy 

 of Sciences before his death were destroyed in the great fire of 1906, 

 with the exception of the types of new species discovered by him, 

 which fortunately were preserved through the foresight of Miss Alice 

 Eastwood, the present Curator of the Herbarium.
