About Index Fungorum

Now hosted at the Royal Botanic Gardens, Kew, a leading UK research institution with over 250 years of botanical and mycological expertise, Index Fungorum provides authoritative, regularly updated taxonomic information and is a key resource for researchers worldwide.

The logo at the top left (the idea came from Ken Hudson who is the present compilor of the Index of Fungi) indicates that the underlying database is both a nomenclator (a database of names with nomenclatural opinions) and potentially a checklist of the fungi of the world (names with taxonomic opinions as either a current name or a synonym). The ‘S’ (from Species Fungorum) encircling the ‘IF’ (from Index Fungorum) graphically illustrates that for any checklist it is essential to have an underlying nomenclatural component.
