The current edition of the International code of botanical nomenclature (Vienna Code) accepts cultures of fungi and algae as types provided that they are preserved in a metabolically inactive state. In this article the authors outline a procedure for cryopreserving type cultures at ultra-low temperatures (<−135°C), thus ensuring that the material is held in a stable, metabolically inactive state. This procedure would allow direct access to live ex-type cultures, facilitating traditional research as well as molecular, metabolomic and proteomic studies.
