Abstract:
The debates over the requirement of the International Code of Nomenclature for algae, fungi, and plants (ICNafp)
for a viable specimen to represent the name-bearing type material for a species or infraspecific taxon have a long
history. Taxonomy of fungi commonly studied as living cultures exemplified by yeasts and moulds, strongly depend
on viable reference material. The availability of viable cultures is also particularly useful for several groups of filamentous and dimorphic fungi. While the preservation of metabolically inactive cultures is permitted and recommended by the ICNafp, there is room for improvement. Below, we review the history and current status of cultures
as the name-bearing type material under the Code. We also present a roadmap with tasks to be achieved in order
to establish a stable nomenclatural system that properly manages taxa typified by viable specimens. Furthermore,
we propose setting up rules and defining the nomenclatural status of ex-type cultures under Chapter F, the section
of the ICNafp that includes provisions specific to names of fungi.
