Interpretive Summary: Fungi that attack plants cause over $25 billion in crop losses in the United States annually. In order for people involved in agriculture to communicate about fungi, the fungi need accurate names. For years, the fact that two names were allowed for a single fungal species created a great problem, but recently scientists agreed to use just one scientific name per species. The first step in changing to one scientific name is to determine which genus (i.e., a closely related group of species) should be used. In this paper, recommendations are provided for the genus names to use for a major group of fungi that cause diseases of crop plants and trees. These recommendations are significant because they provide the basis for updating the global database of scientific names of fungi important to agriculture at Consequently, this research will be used by scientists, extension personnel and plant quarantine officials who use accurate scientific names to communicate about diseases caused by fungi and thereby keep American agriculture safe and productive.

Technical Abstract: In advancing to one name for fungi, this paper treats generic names competing for use in the order Diaporthales (Ascomycota, Sordariomycetes) and makes a recommendation for the use or protection of one generic name among synonymous names that may be either sexually or asexually typified. A table is presented that summarizes these recommendations. Among the genera most commonly encountered in this order, Cytospora is recommended over Valsa and Diaporthe over Phomopsis. New combinations are introduced for the oldest epithet of important species in the recommended genus. These include Amphiporthe tiliae, Coryneum lanciforme, Cytospora brevispora, C. ceratosperma, C. cinereostroma, C. eugeniae, C. fallax, C. myrtagena, Diaporthe amaranthophila, D. annonacearum, D. bougainvilleicola, D. caricae-papayae, D. cocoina, D. cucurbitae, D. juniperivora, D. leptostromiformis, D. pterophila, D. theae, D. vitamegaspora, Mastigosporella georgiana, Pilidiella angustispora, P. calamicola, P. pseudogranati, P. stromatica, and P. terminaliae.
