XII International Mycological Congress: report of Congress action on nomenclature proposals relating to fungi.

Abstract

Procedures, appointments and outcomes of the Fungal Nomenclature Session (FNS) of the XII International Mycological Congress (IMC12) are summarized, including the composition of the Fungal Nomenclature Bureau and the Nominating Committee of the IMC. Between 124 and 322 mycologists attended the three sessions of the FNS, at which formal proposals to amend Chapter F of the International Code of Nomenclature for algae, fungi, and plants were debated. The 15 proposals considered included eight "from the floor", five of which were withdrawn prior to the FNS. One of the withdrawn proposals was directed to the Editorial Committee for Fungi, in relation to adding examples of best practice when citing living cultures as types. Among the seven proposals published in Taxon, one proposal with a high "no" vote in the Guiding Vote was not re-introduced. Discussion on one proposal led to the authorization of a Special-purpose Committees on "Genomes as Types for Fungi". For the eight proposals that were put to a vote, two proposals were rejected and six proposals were accepted. The accepted proposals: (1) clarified that a proposal to conserve a name with a conserved type does not require citation of a typification identifier; (2) clarified procedures to protect and reject names of fungi; (3) removed the need to list synonyms of protected names in the Code appendices; (4) clarified that an earlier homonym of a sanctioned name remains unavailable if the sanctioned name is rejected outright; (5) recommended that culture collections or biological resource centres where cultures are lodged should be "public"; and (6) recommended that when original type cultures are lost, neotypification should utilize the progeny of ex-type cultures. Appointments made by the FNS included the Secretary of the Fungal Nomenclature Bureau for IMC13, the officers and members of the Editorial Committee for Fungi, and the officers and members of the Permanent Nomenclature Committee for Fungi. Decisions and appointments of the FNS were ratified in a resolution accepted by the plenary session of the Congress.
