A new nomenclature for fungi

Important changes brought about by the Melbourne International Code of Nomenclature for Algae,FungiandPlantsare briefly reviewed concerning a clarification of the spelling and typification of sanctioned fungal names, the recognition of electronic publication for the validity of nomenclatural novelties, permission to use English diagnoses or descriptions for their valid publication, and the requirement of registration of such novelties with an identifier number issued by a registration repository. The most drastic change, the abolishment of the former Article 59 permitting a dual nomenclature for pleomorphic fungi, is outlined in more detail. From 2013 onwards the introduction of two names for different morphs of a fungus will render both names invalid. In the choice between names applied to anamorphs and teleomorphs priority would have free play. To avoid countless ensuing name changes, the previous rule-determined system of nomenclature is being replaced by a committee-determined list-based nomenclature. Suggestions for reducing the necessary name changes to a minimum have been proposed.
