Fungi have come into demand as sources of biological control agents and of particular physiological active substances. Recent studies indicate that fungi can be the prime cause of sinusitis, asthma, and allergenic troubles. Some fungi can be useful however, and can be used to improve the overall quality of human life. With very few books available on the subject of soil and seed fungi, Tsuneo Watanabe's book remains the only work that details information on techniques for isolating, culturing, and identifying soil and seed fungi. This new edition of "Pictorial Atlas of Soil and Seed Fungi" describes more than 350 fungal species, including: 46 Mastigomycetous species; 33 Zygomycetous species; 36 Ascomycetous species; 9 Basidiomycetous species; and, 240 Deuteromycetous species. In this atlas, Watanabe presents the results of his soil-borne plant disease studies including pathological and mycological aspects. "The Pictorial Atlas of Soil and Seed Fungi, Second Edition" includes 45 new fungal species illustrated in brilliant detail using original photomicrographs and line drawings.
