Seriously, while Aspergillus and Penicillium are treated as form genera in the Eurotiaceae, The oospores of six species of the relatively unimportant Albugo are figured. ForР”В®xample, Phytophthora infestans is the only specific example of this important genus, while There are several instances of inconsistent treatment. Rectified, but it is most unfortunate that the majority of the excellent figures and photographs still give no scale. The very few points which were mistaken or not clear in the first edition have been Scattered in the taxonomic treatment, can very easily be traced. The glossary has been slightly expanded and the index has been divided into authorР”Р„nd subject categories: it is comprehensive, and biological groups, which are widely There is a shortР”Р„ccount of the lichens, but strangely, no more than a passing reference to mycorrhiza. The treatment of the Basidiomycetes is relatively little changed from the first edition, although the Sporobolomycetaceae is now included here rather than in the Deuteromycetes. The parasexual cycle, and moniliaceous pathogenic fungi. Hughes' classification and its modification by Tubaki. The Deuteromycetes areР”Р„dequately covered on Saccardoian lines, with a welcome mention of the outline of There are some differences from the original treatment. Re-arranged in accordance with Luttrell's views, although, as with the Phycomycetes

(Ascomycetes, Deuteromycetes and Basidiomycetes) the Pyrenomycetes have been Of their own, the Myxomycotina, and are followed by the Phycomycetes, the arrangement of which is based on Sparrow's treatment. Lower Fungi' the Myxomycetes-'the true slime moulds '-are placed in a subdivision Of Uncertain Affinity', and covers the Acrasiales and the Labyrinthulales. The Orders have here been arranged in three groups. This has been interpolated into the taxonomic Of the bacteria have been omitted to make room for a considerable amount of recent The summary at the end of each chapter and the account In the second edition a number of changes have been made in the general layout andР”Р„lso in the individual chapters. Spectrum of students of mycology, especially when use has been made of the references It has proved, in fact, to be useful to a much wider 270, 1953) has found great favour as a text written specifically for Over the last ten years the first edition of Introductory Mycology by Prof. (New YorkР”Р„nd London: John Wiley and Sons, 1962.) Pp, 613, 194 figures. The authors are to beР”В¬ongratulated on producing a first-class book which will be valued by students and There must be very fewР”В«iological texts in which the choice and the quality is bettered. Selected with very great care and have been very well produced. Of the book is the exceptionally high quality of the illustrations. In this book the authors haveР”В¬hosen well and their selection has met with very wide approval. That some of their favourite types have been omitted. Great difficulty in selecting the examples for discussion, and most readers usually find Which will be a very considerable help to students.Р”Р„ny authors who attempt to review a wide range of organisms are faced with very Twenty pages summarizing the techniques used in the examination of micro-organisms, This clearly was a difficult section to write as it covers suchР”Р„ wide field. Section III deals with theР”В®cology of micro-organisms. Microbiology but to a wider audience of biologists as well. The chapter on metabolism will be of value not only to students of Than a specialist to follow the literature and to present an adequate review of the Living organisms in the last twenty years that it has become difficult for anyone other There have been so many contributions to the detailed knowledge of the biochemistry of A particularly valuable section of this is Chapter 7 on metabolism. Section II deals with chemistry, metabolism, Structure and life histories are discussed.

In each of the chapters associated with these the general morphology, Section I deals with the bacteria, fungi, protozoa and slime moulds,Р”Р„lgae and viruses. Give a wide review of the morphological, physiological and ecological aspects of theР”Вifferent groups.

The work by Lilian Hawker and her colleagues is highly successful in its attempt to Of the biology of these diverse groups of organisms. The introduction of many new courses embracing a knowledge of bacteria,Р”Р‡ungi, actinomycetes and protozoa has emphasized the need for a general consideration Other countries in separating general microbiology from the dominance of medicalР”В«acteriology. In this respect Great Britain has been somewhat slower than Microbiology as a separate discipline in its own right as distinct from being a hand-maiden This reflects the growing interest and expansion of One of the features of the last ten years has been the publication of a number of booksР”Вealing with general microbiology.
