Data from: Genome resources for seven fungal isolates that cause turfgrass dollar spot disease, including Clarireedia jacksonii and C. monteithiana

    Ascomycete fungi in the genus *Clarireedia* are responsible for dollar spot, one of the most destructive and costly diseases affecting turfgrasses worldwide. Almost all grasses grown as turf are susceptible to dollar spot, including many high value grass species commonly used for golf courses. This Ag Data Commons dataset provides the genome sequences for seven isolates of *Clarireedia* fungi that cause dollar spot disease, including sequences of the two most widespread species, *C. jacksonii* and *C. monteithiana*.

    Data from: Global distribution of mating types shows limited opportunities for mating across populations of fungi causing boxwood blight disease

      Boxwood blight is a disease threat to natural and managed landscapes worldwide. To determine mating potential of the fungi responsible for the disease, *Calonectria pseudonaviculata* and *C. henricotiae*, we characterized their mating-type (MAT) loci. Genomes of *C. henricotiae*, *C. pseudonaviculata* and two other *Calonectria* species (*C. leucothoes*, *C. naviculata*) were sequenced and used to design PCR tests for mating-type from 268 isolates collected from four continents.

      Data from: Condition‐dependent co‐regulation of genomic clusters of virulence factors in the grapevine trunk pathogen Neofusicoccum parvum

        The capability of the ascomycete *Neofusicoccum parvum* to colonize woody tissue, combined with the secretion of phytotoxic compounds, is thought to underlie its pathogenicity and virulence. The repertoire of virulence factors and their transcriptional dynamics as the fungus feeds on different substrates and colonizes the woody stem are described and a highly contiguous genome is assembled and annotated using single‐molecule real‐time DNA sequencing.

        U.S. National Fungus Collections

          The U.S. National Fungus Collections (BPI) are the “Smithsonian for fungi” and are the repository for over one million fungal specimens worldwide - the largest such collections in the world. The collection includes preserved organisms, their parts and products, and their associated data. Information associated with these specimens constitute an enormous data resource, especially about plant-associated fungi. The collections document fungi through time and space for the past 200 years. Data from the labels of more than 750,000 of the specimens have been entered into a database. These labels have information on the host on which the fungus was found and the locality in which the specimen was collected. Sixty percent of these specimens are from the United States and thus represent a large body of information about the fungi in this country.
