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.
