Sobre aquest llibre
Preface: The aim of this book is to present the more important facts concerning the morphology and taxonomy of the continental United States, with some discussion, also, of the more significant facts of morbid histology. Technical description of each division, order, family, genus and species, when important, is given unless the essential characters are to be clearly inferred from preceding keys or text. In order to avoid duplication of the subject matter of "Diseases of Economic Plants" gross descriptions of diseased hosts are omitted from this volume. Bibliographic citations given either in "Diseases of Economic Plants" or in "The Fungi which cause Plant Disease," in general, are not repeated here and the student is referred to these two texts for additional references to literatue. The citations herein given refer to articles either more recent than those of the previous work or are advisable owing to a different viewpoint in the present book. Effort has been made to present at least one illustration of each genus of importance. The keys, for the most part, are abbreviated or otherwise modified from those given in "The Fungi which case Plant Disease." All keys are abridged by the omission of genera or larger groups whose representatives are of minor importance. The author wishes to express thanks for suggestions and criticism of the manuscript to F.W. Tanner who read the portion on Bacteria; G.P. Clinton, Ustilaginales; E.C. Stakman, and H.R. Rosen, Uredinales; C.L. Shear, the anthracnose fungi; E.A. Burt, certain Basidiomycetes; C.D. Sherbakoff, the genera Fusarium and Nectria; and to B.B. Higgins for kindly reading critically the entire book in proof.--F.L. Stevens--Urbana, Illinois, March, 1925.
