INDEX TO AMERICAN SPECIES OF 

 PHYLLOSTICTA 



P. J. Anderson 



In " The North American Phyllostictas " ElHs and Everhart 

 brought together descriptions of all the species of this genus re- 

 ported from North America up to 1900. About 225 species were 

 included. During the eighteen years which have elapsed since the 

 publication of that excellent monograph 41 new species have been 

 described from America north of Mexico, 20 other described 

 species have been reported for the first time, 116 new hosts have 

 been added, transfers have been made to and from the genus, 

 Ascomycefe connections have been established for a few and 

 various changes in names of species and hosts have been pro- 

 posed. There is no one place in the literature where these changes 

 have been recorded and the genus brought up to date. Saccardo 

 lists only a few of the new species. Having found a Phyllosticta 

 on a host new to himself, the collector at once turns to Ellis and 

 Everhart. If he fails to find it there, he is confronted with the 

 prospect of spending many hours, or even days, searching through 

 a staggering array of periodicals to see whether it has been de- 

 scribed. Even if he finds it in " The North American Phillos- 

 tictas " he wonders how many changes it has undergone since 

 1900. His difficulties are not diminished by the changes in names 

 of the host plants since Ellis and Everhart wrote. 



Having had this discouraging experience a few times in work- 

 ing with Phyllosticta, the writer finally resorted to a card index 

 in which he has listed the new species, hosts and various changes 

 with citations, and which he uses as a supplement to the previously 

 mentioned monograph. It is published here with the thought that 

 others also Inay find it useful in saving many tedious hours spent 

 in combing the numberless periodicals, etc., in which a description 

 or report of an American species may be hidden away. 



The species are first listed alphabetically with citations of litera-
