INTRODUCTION 
For several years the U. S. Regional Pasture Research Laboratory, 
the Kentucky Agricultural Experiment Station, and the Division of 
Forage Crops and Diseases have been collecting references to fungi 
reported on species of Medicago, Melilotus, and Trifolium. Because 
of the recently increased use of these legumes as substitutes for nitrog- 
enous fertilizers to conserve nitrogen for our war efforts, it is im- 
portant that all usable information on the diseases of these crops be 
made available to pathologists at once so that their efforts to control 
these diseases may be speeded. This need for assembled information 
has prompted the preparation of this material for publication at 
this time. 
In preparing the publication, which includes a host index, an 
alphabetical list of the fungi with synonyms, and a list of pertinent 
1 Submitted for publication June 1942. This work was conducted under an allotment 
from the Special Research Fund authorized by Title I of the Bankhead-Jones Act of June 
29, 1935, and is a contribution of the U. S. Regional Pasture Research Laboratory, State 
College, Pa.. in cooperation with the Agricultural Experiment Stations of the 12 North- 
eastern States, the Department of Botany, Bacteriology, and Plant Pathology, Louisiana 
State University, the Agronomy Department, Kentucky Agricultural Experiment Station, 
and the Division of Forage Crops and Diseases, Bureau of Plant Industry.

and Disease Survey, for checking many points in the manuscript and locating the original 
descriptions of many of the fungi; to Percy L. Ricker and Roland McKee. Division of 
Foraze Crops and Diseases, for checking the host names; to Alice M. Atkinson, Division
