Supplementary Notes on the Erysiphaceae 
By Ernest S. SALMON, F.L.S. 
Since the completion of my monograph (67)* on the Erysipha- 
ceae, I have had the opportunity of examining a considerable 
amount of further material. This has enabled me to continue the 
study of the critical forms of several species ; to investigate many 
cases of the reported occurrence of a species on an unusual host 
plant; and to extend the geographical range and add further 
hosts for many species. In the following pages will be found an 
enumeration of most of the species of the Erysiphaceae ( follow- 
ing the order in which they are placed in my monograph) and 
under each species are arranged the critical notes, additional local- 
ities, host plants, etc. These records are based on personal ex- 
amination, except in those cases in which they are followed by a 
number placed in brackets. These numbers indicate a published 
record, which will be found in the work of the author quoted 
under the respective number in the bibliography. 
Before proceeding to give these notes, however, mention must 
first be made of several important papers dealing with the Erysi- 
phaceae which have appeared recently. Of taxonomic interest, 
the following must be noticed. Hennings (31), in his “ Fungi 
Japonici,”’ has described the following as new species or varieties : 
Phyllactinia suffulta var. moricola, Microsphaera Japonica, M. sam- 
bucicola, Sphaerotheca Kusanoi, S. phtheirospermi, Uncinula Shirat- 
ana, U. zelkowae, U. clandestina forma Japonica, U. verniciferae, 
* Memoirs Torrey Club, Volume 9. The numbers refer to the bibliography which 
will appear at the close of the article.
