INTRODUCTION This work is the gradual outgrowth of a plan devised to increase the knowledge pertaining to the parasitic fungi of the state of New Jersey. In developing this plan the writer drew freely from such works as, Catalogue of Plants Found in New Jersey by Dr. I el Britton (in the Geological Survey of New Jersey, Report of the State Geologist, 1889, v. 2, pt. 1, p. 25-642), reports and bulle- tins of the New Jersey Agricultural Experiment Station, North American Pyrenomycetes by Ellis and Everhart, North American Flora, Mycologia, Bulletin of the Torrey Botanical Club, Grevillea, Proceedings of the Philadelphia Academy of Natural Science, and publications of the United States Department of Agriculture. The writer had ample opportunity during the summers of 1912 to 1917, inclusive, to collect and preserve parasitic fungi in the state of New Jersey. This material and “fungi exsiccati” deposited in the herbaria of the New Jersey Agricultural Experiment Station and the New York Botanical Garden afforded the writer excellent opportunities to study the fungous parasites. The plan formulated at first was to list all fungous parasites recorded for the state of New Jersey and supplement this list with their descriptions and drawings of specimens illustrating the respec- tive genera. This plan, however, was abandoned because many specimens collected and recorded by the pioneer botanists had been incorrectly determined. It was finally decided to publish descrip- tions and illustrations only of those species which had been studied in the laboratory. Whenever possible, specimens collected in New Jersey were studied. When no New Jersey material was available specimens from neighboring states were examined. To gain a broader view of the nature of fungous parasites, cul- tures were made in many cases on agar media or on the natural host. Whenever possible, therefore, spore measurements and the growth on nutrient media were compared with those displayed by the para- (3) site on its natural host. In case the original descriptions were meager, inaccurate or obsolete, the descriptions were amplified. Credit is given at the proper place when the description is taken verbatim from a monograph, etc. . All the drawings are original and were made by the author. The same microscope and camera lucida were used and therefore all the fungi were drawn on a uniform scale. The magnification in every instance is appended to the description. To avoid confusion a: generic name of long standing was used. A reference at the proper place was made to the recent terminology. The writer wishes to thank the members of the staff of the New York Botanical Garden for the permission to examine specimens in the Cryptogamic herbarium, for the library facilities and for many helpful suggestions. The writer is also under great indebtedness to Prof. J. C. Arthur, who not only determined the rusts but freely offered advice and criticised that portion devoted to the Uredinales, to Dr. G. P. Clinton for determining the smuts, and to Prof. F. C. Stewart, Geneva, N. Y., Doctors R. A. Harper, W. A. Murrill, F. J. Seaver, A. B. Stout, Donald Reddick, V. B. Stewart, C. L. Shear, J. J. Davis and F. D. Fromme for helpful suggestions. The writer is also under great indebtedness to Prof. Melville Thurston Cook, head of the Department of Plant Pathology of the New Jersey Agricultural Experiment Station, who directed the work, for his encouragement, advice, helpful suggestions and cooper- ation in preparing the descriptions, for the arrangement of the plates and for reading the proof.
