Therefore, its presence in Washington has the potential to impact the state's populace and trees, including the native bigleaf maple, <i>Acer macrophyllum</i>. To better determine the distribution of <i>C. corticale</i> in western Washington, <i>A. macrophyllum</i> was surveyed on 50 Washington State Park properties. Bark samples were collected from trees with fruiting bodies resembling those of <i>C. corticale</i> and cores were removed from mature asymptomatic trees. The presence of <i>C. corticale</i> was confirmed using nested PCR. <i>Acer macrophyllum</i> with fruiting bodies of <i>C. corticale</i> were well distributed throughout western Washington, with an 89% detection rate at surveyed Park properties containing <i>A. macrophyllum</i>.

Fungi native to Minnesota were isolated and tested in laboratory and field assays to evaluate their antagonism towards <i>H</i>. <i>irregulare</i>. One management strategy for plant pathogens, and especially <i>H. irregulare</i>, is to use fungi as biological control agents. A successful biological control agent used to manage root rot disease caused by <i>H. irregulare</i> is the fungus <i>Phlebiopsis gigantea</i>. The goal of this research was to screen different native fungi, including <i>P. gigantea</i>, against <i>H. irregulare</i> and examine and quantify their interactions in vitro and ex vitro. A set of four different antagonism assays were conducted. These assays served as a screening process involving both the laboratory and the field. Interactions were first examined with dual inoculation studies on media and wood discs of red pine (<i>Pinus resinosa</i>). These assays demonstrated strong inhibition and limited growth of <i>H. irregulare</i> by select fungi, including <i>Phanerochaete livescens</i> and <i>P. gigantea</i>. Another assay involved using soil microcosms and wood wedges of red pine. This allowed for a different examination, as wood wedges were inoculated with a candidate antagonistic fungus and placed in soil microcosms with <i>H. irregulare</i>. The opposite interaction was also examined with wedges inoculated with <i>H. irregulare</i> and then placed in soil microcosms containing different candidate fungi. In the field, large wood discs were placed around stumps and inoculated with candidate fungi in a red pine plantation infected with <i>H. irregulare</i>. Certain fungi performed well in different assays, but across all assays, <i>P. gigantea</i> performed the best. The antagonism of <i>P. gigantea</i> was most noticeable on wood discs and wood wedges used in vitro, as <i>H. irregulare</i> was not able to be reisolated from these substrates.
