references, it was possible to check the files of the late Dr. A. B. 
Seymour at the Farlow Herbarium, Harvard University, and of the oe 
Division of Mycology and Plant Disease Survey at Washington. f 
From a total of about 3,000 references, over 1,700 were selected and 
are included in the literature list. In order to conserve space, Oude- 4 
man’s Enumeratio Fungorum, Seymour’s Host Index, Farlow’s Host | 
Index, the United States Department of Agriculture Bulletin No. 
1366 (A Check List of Diseases of Economic Plants in the United 
States), most text books, and to a large extent the references in the | 
Plant Disease Reporter were omitted from the literature cited. ‘ 
The fungi in the host index are listed alphabetically except where q 
bracketed. In these latter instances, the first name is supposedly the ‘ 
perfect stage of the fungus. An asterisk after a name indicates that 
the fungus has been reported in the United States either from a field - 
collection or as the result of an inoculation test. A question mark 
after the name of a fungus in the index indicates that the report 
is doubtful or incorrect in some way. 
In the alphabetical list of fungi, perfect and imperfect stages are 
bracketed together also, but, in addition, the imperfect stages are 
listed in their proper alphabetical position with cross references. to 
their perfect stages. F 
The synonymy given is based largely on the literature. Synonyms 
are listed only under the accepted species names. To have listed 
them alphabetically also, with cross references to the accepted names, 
would have increased the usability of this compilation but would 
have increased its size considerably. Species delimited primarily on 
pathogenicity in most cases have not been recognized. The original 
place of publication follows a fungus name, except in those cases,. 
chiefly European exsiccati, where original descriptions could not be 
located. A reference to Saccardo’s Sylioge Fungorum is included . 
for most of the fungi. A citation from Wollenweber and Reinking’s: 
Die Fusarien is included for each species of /usarium. 
The literature cited is listed alphabetically, and the references are 
numbered consecutively. The numbers fellowing each fungus refer 
to the numbers in the literature cited. In nearly all cases the orig- 
inal publications were checked. Where serious doubt occurred as to 
the accuracy of a report a question mark follows the citation number 
and the publication is cited again under the fungus believed to be 
the correct one if it could be determined. It was impossible in some 
publications to determine with certainty the identity of the fungi 
reported. Consequently, in some cases it was necessary to cite such 
publications under several fungi. 
Host names were checked for the authors by Percy L. Ricker, 
assistant botanist, and Roland McKee, senior agronomist, Division of 
Forage Crops and Diseases. Several species names known to be er- 
roneous, through mistakes in spelling or other reasons, are included,. 
since fungi have been reported on them in the mycological or phyto- 
pathological literature. These names are italicized and are followed 
by a question mark. Possible corrections for such names are placed 
in parentheses following the question mark. 
Synonyms of the host species upon which fungi have been reported 
are listed in italics in their proper aiphabetical order without paren- 
theses and are listed again in italics within parentheses following: |
