A handbook for all who work with or are interested in fungi (including lichens and yeasts). This new edition, with 20,000 entries, provides the most complete listing of generic names of and terms used to describe fungi available. For each genus, the authority, the date of publication, status, systematic position, number of accepted species, distribution, and key references are given. Diagnoses of families, orders and higher categories are included for most groups. In addition, there are biographic notes, information on well-known metabolites and mycotoxins, and broad accounts of almost all pure and applied aspects of the subject (including citations of important literature).
