| description | Globally, forest decline and tree mortality are rising due to climate change. As one of the important afforestation trees in northeast China, <i>Pinus sylvestris</i> var. <i>mongolica</i> is suffering from forest decline and the accompanying pests. Certain fungi from the ophiostomatalean contribute to forest pest outbreaks and can be pathogenic to pine trees. However, only a limited number of ophiostomatalean fungi associated with beetles infesting <i>Pinus sylvestris</i> var. <i>mongolica</i> have been identified. In this study, 293 ophiostomatalean fungi were isolated from <i>Acanthocinus griseus</i>, <i>Ips chinensis</i>, and <i>Pissodes nitidus</i> infesting <i>Pinus sylvestris</i> var. <i>mongolica</i> in Heilongjiang Province, including <i>Graphilbum griseum</i> sp. nov., <i>Gra. nitidum</i> sp. nov., <i>Graphilbum</i> sp., and <i>Ophiostoma ips</i>. <i>Ophiostoma ips</i> was the dominant species, followed by <i>Graphilbum</i> sp., <i>Graphilbum griseum</i>, and <i>Gra. nitidum</i>, which accounted for 73.38, 17.41, 7.17, and 2.05% of the isolated ophiostomatalean fungi, respectively. Fungi associated with different beetles are diverse, even within the same host. This study deepens our understanding of the pest-associated fungi of <i>P. sylvestris</i> var. <i>mongolica</i> and provides a basis for exploring the causes of forest decline. |
