A comprehensive taxonomic study of four families of Australasian Helotiales has been conducted. Details of the taxonomy of constituent species of Geoglossaceae, Orbiliaceae, Sclerotiniaceae and Hyaloscyphaceae from this region are presented, and a description of the type genus of the type family, Leotiaceae, is given for comparative purposes. In addition, an historical survey of the collection of Australasian discomycetes is included and notes on the principal collectors given in an appendix. The presentation of the taxonomic account takes the form of a key to the families of Helotiales occurringi n Australasia, keys to the accepted genera in each included family andto the species in each genus. A full description and discussion of the nomenclatural and taxonomic status of each genus is provided and all species are fully described and illustrated. The complete synonymy of each species is given, together with a detailed discussion andc omparison of related taxa. All material relevant to the Australasia rregion has been examined and a total of 38 genera, 124 species and 5 infra-specific taxa are recognized.
