A comprehensive and detailed account of the equipment and techniques used in the microscopic study of fungi. The book includes useful practical advice, based on the wide experience of several well-known mycologists. Presented and written in an accessible style, the text is complemented by good illustrations and clear summary tables. Spiral bound to ensure the book will lay flat during use.
This is the first English language version of Microscopie & Champignons, now collated from the previous versions and parts thereof into a single corrected and enlarged sixth edition. The book should be invaluable to anyone wanting to develop their skills in fungal identification as well as incidentally providing something of an illustrated glossary of fungal terms.
