Fungi. By Dame Helen Gwynne-Vaughan. (Cambridge University Press. 35s. net.)—The
importance of the fungi is due in part to the fact that they cause so many destructive diseases in plants of economic or ornamental value and in part to their instrumentality in bringing about fermentations and other processes some of them so commonly utilized in our everyday life as to make us dependent to a very large extent on fungoid activities. In her general account of this group Dame Helen Gwynne-Vaughan has given us an able rind comprehensive survey of the structure and physiology of these organisms and has critically discussed the phenomena underlying their various activities. The special part is concerned with a detailed account of the two sub-groups with which our author's researches have dealt mostly. The work is a model of scholarly care and lucidity. The author is to be heartily congratulated on her achievement which will place all interested in this group under a debt of gratitude to her.
