(340) Proposal to add a Note of interpretation and guidance to Articles 42.1 and 42.2

This proposal is based on the registration system as implemented in Art. 42 the Melbourne Code (McNeill & al. in Regnum Veg. 154. 2012) for organisms treated as fungi, including fossil fungi and lichen-forming fungi. The purpose of this proposal is to prevent names being changed between registration and effective publication, i.e., to “lock” the name registered to the identifier issued, and to clarify, with respect to the citation of the identifier, that a name is not validly published if in the intended protologue the identifier is mis-cited or if the name is changed to one that is different from that which was registered. Concurrent proposals by others (Barkworth & al. in Taxon 65: 658. 2016) envisage three mechanisms for registration: proactive (prepublication), synchronous (concurrent to publication), and retrospective (post-publication); should there be a change from the current system for fungi this Note would be superfluous.
