Searching the Index Fungorum database

Searching the Index Fungorum database, and the other databases on this site, works best if you have ‘cookies’ enabled on your browser. Disabling cookies will stop you from navigating between pages of records and traversing the taxonomic hierarchy.

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.

Search for publication and other details of a fungus name by entering either the name or the epithet (both specific and infraspecific epithets are searched together). Your entry can be right-truncated (do not add a * or % to the end of the search string - we will do that for you), e.g. ‘Agaricus am’ will find all names within the genus ‘Agaricus’, where the first two letters of the epithet start with ‘am’.

The database search restricts you to 6000 records so if you enter something as vague as ‘A’ you will not get all the records – try and be a bit more specific. The restriction is sufficient to return all records for the largest genus (Lecidea), if you really want to scroll through 30 pages of results, or the most common epithet. Please be kind to our server and be specific, literally!

Names with blue links are names for which there is no taxonomic opinion available, red links are misapplied names (names which have been used in a sense which is different from that as represented by the type of the name), green links are names where a taxonomic opinion has been expressed and lead directly to the approporiate page in the Species Fungorum web site.

Click on an entry to see more data. Full publication details are provided for some entries from CABI’s Index of Fungi. However, full details of names published during the last 5 years have been omitted. If you want these data then take out a subscription to the publication and support it's production; see the final paragraph in the Index Fungorum Partnership agreement for details.

Entries with ‘[GSD]’ or ‘[RSD]’ have onward links to Global Species Databases (part of Species Fungorum) or Regional Species Databases and full synonymy data.

For most entries the taxonomic hierarchy attached to a name is either derived from the nomenclatural position of the genus through its type (thus Helotium appears in the Tricholomataceae because the type of Helotium is a basidiomycete), or in some cases through the presumed position based on an assesment of associated homotypic names. Only in GSD data, or other data for which a taxonomic opinion is available (and which contribute to the Catalogue of Life - see Species 2000), is the correct taxonomic position of a name known through the position of the currently accepted name.

The database has been derived from a number of published lists including Saccardo’s Sylloge Fungorum, Petrak’s Lists, Saccardo’s Omissions, Lamb’s Index, Zahlbruckner’s Catalogue of Lichens (comprehensive for names at species level only but with an increasing number of names of infraspecific taxa) and the Index of Fungi. A name record will usually have a reference to an entry in one or more of these published lists in addition to other data derived from numerous acknowledged sources. Author citations conform with the Brummitt & Powell standard (now searchable on-line here or through IPNI), or are indicated '{?}' thus.
