Interpretive Summary: Everything needs a name in order to effectively communicate about it, including fungi that cause diseases. For years two names of fungi were allowed but recently it was decided to change to just one scientific name for fungi. This is in agreement with all other groups of organisms. The first step in changing to one scientific name is to determine which genus should be used. Numerous papers have been published with recommendations on which name should be used for major groups of plant pathogens but some have been overlooked. In this paper, we make recommendations for these overlooked fungal groups, including important fungi that cause diseases of crop plants and trees, based on all available information including DNA sequences. This research will be used by scientists and plant quarantine officials who use the accurate scientific names to communicate about diseases caused by fungi and to keep American agriculture safe.

Technical Abstract: With the change to one scientific name for fungi, generic names representing sexual and asexual morphs have been evaluated to determine which name to use when two names represent the same genus and thus compete for use. In this paper generic names of the Pucciniomycotina and Ustilaginomycotina are evaluated based on their type species to determine which names are synonyms. Twenty-one sets of sexual- and asexual-typified names in the Pucciniomycotina and four sets in the Ustilaginomycotina were determined to be congeneric and compete for use. Recommendations are made for which generic name to use. In most cases the principle of priority is followed. However, nine generic names in the Pucciniomycotina are recommended for protection, specifically: Classicula over Naiadella, Gymnosporangium over Roestelia, Helicobasidium over Thanatophytum and Tuberculina, Heterogastridium over Hyalopycnis, Melampsorella over Peridermium, Milesina over Milesia, Phragmidium over Aregma, Sporobolomyces over Rhodomyces and Blastoderma, and Uromyces over Uredo. In addition, eleven new combinations are made as follows: Agaricostilbum elviae, Blastospora juruense, B. subneutrophila, Cronartium bethelii, C. harknessii, C. kurilense, C. sahoanum, C. yamabense, Melampsora cedri, Milesina polypodii and Prospodium cruscula.
