This manual covers all groups of fungi and fungus-like organisms and includes over 500 diagrams and line drawings. Descriptions of major groups (phylogenetic and artificial), simplified keys to family, and an illustrated glossary enable placement of common fungi into the appropriate taxonomic category. Text and glossary are coordinated to introduce fundamentals of mycological terminology. Over 30 pages of references are provided for literature on identification of cultures and specimens, and references are also given for contemporary phylogenetic research on each major taxonomic group.

Marine Mycology: The Higher Fungi deals with the higher marine fungi, i.e., Ascomycotina, Basidiomycotina, and Deuteromycotina. This book combines features of a monograph with those of a text. It includes sections on ecological groups of fungi and other topics, such as phylogeny, ontogeny, physiology, and vertical and geographical distribution, providing information on known facts and open questions. The taxonomic-descriptive part contains complete descriptions of each genus and species, together with substrates, range, etymology of generic and specific names, and literature. There are keys for all species within a given genus, and a general illustrated key leads to the individual species. The taxonomic section is based on examinations of almost all of the filamentous marine fungi, and unpublished data on new hosts and geographical distributions are included for many species. The filamentous higher marine fungi are represented by 149 Ascomycetes, 4 Basidiomycetes, and 56 Deuteromycetes. The majority, namely 191 (91%) of the filamentous fungi, are obligately marine species, whereas the remainder are facultatively marine. One new species and seven new combinations are proposed. The yeasts are treated in a separate chapter and comprise 177 species or varieties.

It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the respon sibility for the fourth edition, the fifth edition, and now the sixth edition was not taken lightly. The task has been a formidable one. I have always had great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the three editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in de veloping the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. . . " This revision of the Handbook retains the same general format contained in the previous editions. The chemieals and pesticides regulations have been updated; major taxonomie changes have been made in the bacteria, fungi, nematodes and viruses; the changing pieture in diseases caused by viruses and/ or viruslike agents have been described. New host plants have been added, and many recently reported diseases as weIl as previously known diseases listed now on new hosts have been included.

Westcott’s Plant Disease Handbook, 7th Edition, should be useful to anyone with a keen interest in gardening. The seventh edition uses the traditional convenient format of previous editions providing easy access to essential information quickly with special dictionary-type entries on plant hosts and on symptoms. It provides useful cross references, indexes, illustrative plates of 34 key diseases, and 40 black and white illustrations of other diseases. New and updated material includes: significant taxonomic changes in fungi, bacteria, viruses and nematodes, and recently discovered diseases and new hosts for previously known plant-pathogens.
