Originally published in 1989, this book presents a detailed analysis of nitrogen, phosphorus and sulphur utilization by fungi. Based on the 1988 British Mycological Society symposium, it is broadly based, covering four basic areas: physiology and metabolism of nitrogen, phosphorus and sulphur by fungi; role of these minerals in pathogenic relationships with plants; their role in mutualistic relationships with plants; and the role of saprotrophic fungi in cycling of the elements through ecosystems. This book will be of interest to research workers, advanced students and teachers of mycology, plant pathology, plant nutrition and soil ecology.
