The Checklist of Fungi of Malaysia aims to provide the latest information on the fungi known to occur in Malaysia and is compiled from published documents scattered in the literature. It has taken five years to prepare and documents the rich diversity of fungi to be found in country. It is aimed at those involved in research, and teaching of mycology, and related fields such as forestry, agriculture, ecology, biogeography and systematics. It is hoped that the Checklist of Fungi of Malaysia will become an essential part of the mycologist's and plant pathologist's library and serve as a catalyst to continued fungal biodiversity studies in Malaysia.
