Royal Botanic Gardens, Kew and Springer are collaborating with JSTOR to digitize, preserve and extend access to Kew Bulletin. Summary. All species of the genus Termitomyces Heim (Agaricales, Pluteaceae) which occur throughout southeast Asia are collectively considered for the first time. Illustrated accounts for all the accepted species are provided, together with a key to species. Termitomyces was described by Heim (1942a) for a group of termitophilous agarics found in central Africa. The Tribe Termitomceteae (Jfilich) Singer has been placed within Tricholomataceae Heim ex Pouzar by Singer (1986), close to the Tribe Lyophylleae Kiihner ex Bas, based upon the presence of siderophilous granulation detected in the basidia. Jiilich (1981) raised the group to family level, Termitomycetaceae, and placed it alongside Amanitaceae Roze and Torrendiaceae Jiilich in the Amanitales Jiilich. Pegler (1986) preferred to accommodate the genus Termitomyces Heim within Pluteaceae Kotl. & Pouzar, largely on the basis of the pluteoid habit, with densely crowded, free lamellae which rapidly decay, the pink spore deposit, the type of hymenial cystidia, and the basidiospores which often develop a wall-structure with two teguments and the presence of an open-pore hilum (Pegler & Young, 1971). The main difference from other genera in Pluteaceae lies in a hymenophoral trama with divergent, rather than convergent, hyphae in the basidiomatal primordia, together with the termitophilous association. Singer (1945) separated Termitomyces microcarpus (Berk. & Broome) Heim in order to propose a new genus, Podabrella, on the basis of the epigeous habit and lack of pseudorhizal development, and to which he added some neotropical, non-termitophilous species. Zang (1981) examined some collections from Yunnan Province, P. R. China, and proposed a new genus, Sinotermitomyces, which may be separated from Termitomyces as follows:

This dictionary, now in its sixty-fifth year, contains more than 21 000 entries and provides the most complete listing available of generic names of fungi, their families and orders, their attributes and descriptive terms. All organisms traditionally studied by mycologists are covered including lichens, mushrooms, slime moulds, water moulds and yeasts. 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, this 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.
