The serious study of mycology in South Africa started with the appointment, in 1905, of I. B. Pole Evans as mycologist in the Transvaal Department of Agriculture. Records of South African fungi have been continued by other workers, particularly P. A. van der Byl and by Dr. Ethel Doidge herself. These records have now been brought together in this large volume of over 1, 000 pages, which is an important addition to the world's mycological literature. Many of the fungi included have a special mycological interest because of their unusual structure or their physiological relations with their substrata. Horticulturists will be interested in the records of those fungi which attack subtropical fruit trees; lists of fungi found on Citrus spp. are on pp. 864-8, and 17 fungi on Persea americana (avocado) on p. 829. It will prove a useful book of reference for horticulturists and plant pathologists, particularly with regard to the distribution of the fungous parasites of crop plants. H.W.
