This is the one essential handbook for all who work with or are interested in fungi (including lichens, slime moulds, yeasts and fungal analogues).This new edition, with more than 21,000 entries, provides the most complete listing available of generic names of fungi, their families and orders, their attributes and descriptive terms. 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 and details of orders and higher categories are included for all groups of fungi. In addition, there are biographic notes, information on well-known metabolites and mycotoxins, and concise accounts of almost all pure and applied aspects of the subject (including citations of important literature).All information has been updated as necessary since the publication of the ninth edition in 2001. In addition the tenth edition has the following new features: a completely new classification of the Kingdom Fungi based on recent multi-gene phylogenetics research; a major revision of the classification of the Basidiomycota and substantial modification of the "basal" groups; further integration of anamorphic and teleomorphic genera in the classification; enhanced distinctions between the true fungi and unrelated groups traditionally studied by mycologists; and, improved information on references to publications.
