Notes on rust fungi in China 3. Puccinia adenocauli comb. nov. and its life cycle and new host

The heteroecious and macrocyclic life cycle of Aecidium adenocauli was proved with field observations and inoculation experiments in China. Its spermogonial and aecial stages were produced on Adenocaulon himalaicum, and uredinial and telial stages were produced on Carex onoei, which is a new host for this rust fungus. Uredinial and telial stages (teleomorph) of this rust fungus were formerly described as Puccinia carici-adenocauli from Japan. However, the current International Code of Nomenclature (ICN (Melbourne)) has abolished the distinction between "anamorph" names and "teleomorph" names, and we propose the new combination Puccinia adenocauli, based on Ae. adenocauli 1913, which now has priority over P. carici-adenocauli 1999. Its neotype and epitype are also designated.
