The ICTF has several Subcommissions who collaborate on the organization of workshops, conference symposia, and the development of taxonomic resources for their user communities. There are also affiliated Commissions that share a common vision for the development of cooperative fungal taxonomy, although they are not formally under the ICTF umbrella. In August 2011, dramatic changes in the rules for naming fungi were announced, and the international mycological community is mobilizing to develop a single name system for fungal species, necessitating the need to establish a number of less permanent Working Groups focused on specific groups. The ICTF and the Nomenclatural Committee for Fungi (NCF) are cooperating in coordinating the international response to the rule changes. The Subcommissions, Affiliated Commissions and Working Groups listed below are where the nomenclatural discussions will occur.

ICTF Subcommissions (see Members for all associated members)

  • International Subcommission for the Taxonomy of Phytopathogenic Fungi
    • Pedro Crous (Co-Chair), Amy Rossman (Co-Chair)

The aims of this subcommission are to define fungal names in the following initial projects: 

1) A list of common plant pathogenic fungi (this is a tentative list that we are working on, then recollect and designate epi- or neo-types for those taxa as needed)

2) The genera of Fungi project, but specifically aimed at settling the names of Genera of Phytopathogenic Fungi

3) Fungi of quarantine importance (the list varies per country).

  • International Subcommission on Colletotrichum Taxonomy
    • Lee Cai (Chair), Bevan Weir (Secretary)


  • International Subcommission on Fusarium Taxonomy
    • David Geiser (Chair)

This is also a subcommission of the International Society of Plant Pathology Commission on Fusarium. There are two major resources developed by this subcommission. The first is the Fusarium nomenclatural database now maintained on the website of the Centraalbureau voor Schimmelcultures (http://www.cbs.knaw.nl/fusarium/BioloMICS.aspx). The second is the DNA sequence database for identification maintained by the Fusarium Research Centre at Pennsylvania State University (http://plantpath.psu.edu/facilities/fusarium-research-center). This subcommission meets regularly at the Fusarium workshops associated with each International Congress of Plant Pathology.
