The practice of giving separate names to the different forms of pleomorphic fungi has been debated since the middle of the 19th century. In 2011, the Amsterdam Declaration on Fungal Nomenclature made the case for an orderly transition to a single-name nomenclature system. Soon after, the one fungus, one name principle was codified in the International Code of Nomenclature for algae, fungi, and plants (Melbourne code).
Nothing is ever easy in the world of fungi.
