Article 42

• For names of new taxa, new combinations, names at new ranks, or replacement names designating organisms treated as fungi (including fossil fungi and lichen-forming fungi) under this Code (Pre. 8) and published on or after 1 January 2013, the citation in the protologue of the identifier issued by a recognized repository for the name (Art. 42.3) is an additional requirement for valid publication.
  • The protologue of Tetramelas thiopolizus (Nyl.) Giralt & Clerc (2011) included the citation “MycoBank no.: MB561208”. Such citation of an identifier issued by a repository appointed by the Nomenclature Committee for Fungi (see Div. III) will be necessary for valid publication of new fungal names on or after 1 January 2013.
• For an identifier to be issued by a recognized repository as required by Art. 42.1, the minimum elements of information that must be accessioned by author(s) of scientific names are the name itself and those elements required for valid publication under Art. 38.1(a) and 39.2 (validating description or diagnosis) and Art. 40.1 and 40.7 (type) or 41.5 (reference to the basionym or replaced synonym). When accessioned and subsequently published information for a name with a given identifier differ, the published information is considered definitive.
  • Issuance of an identifier by a recognized repository presumes subsequent fulfilment of the requirements for valid publication of the name (Art. 32–45) but does not in itself constitute or guarantee valid publication.
• The Nomenclature Committee for Fungi (see Div. III) has the power to (1) appoint one or more localized or decentralized, open and accessible electronic repositories to accession the information required by Art. 42.2 and issue the identifiers required by Art. 42.1; (2) cancel such appointment at its discretion; and (3) set aside the requirements of Art. 42.1 and 42.2, should the repository mechanism, or essential parts thereof, cease to function. Decisions made by this Committee under these powers are subject to ratification by a subsequent International Mycological Congress.

Recommendation 42A

• Authors of names of organisms treated as fungi are encouraged to (a) deposit the required elements of information for any nomenclatural novelty in a recognized repository as soon as possible after a work is accepted for publication, so as to obtain accession identifiers; and (b) inform the recognized repository of the complete bibliographical details upon publication of the name, including volume and part number, page number, date of publication, and (for books) the publisher and place of publication.
• In addition to meeting the requirements for effective publication of choices of name (Art. 11.5 and 53.6), orthography (Art. 61.3), or gender (Art. 62.3), those publishing such choices for names of organisms treated as fungi are encouraged to record the choice in a recognized repository (Art. 42.3) and cite the accession identifier in the place of publication.
