|a Chestnut blight is caused by the fungus Cryphonectria parasitica. As one of the most ecologically important diseases of Castanea spp., C. parasitica can rapidly kill trees. In Europe, mitigation of disease severity took place spontaneously through colonization of C. parasitica by mycoviruses, which reduced the virulence of the fungus. In the framework of a survey, 138 C. parasitica isolates were identified, and virulent/hypovirulent phenotypes were determined through morphological properties and pathogenicity tests. For a pool of four hypovirulent isolates, dsRNA was extracted, cDNA synthesized, and a library subjected to next-generation sequencing. The bioinformatics analysis allowed detecting and reconstructing the complete genome of Cryphonectria hypovirus 1 (CHV-1), denoted as CHV-1 Marche. When compared with the available genomes of other hypoviruses that affected the virulence of C. parasitica, available in databases, CHV-1 Marche showed some nucleotide diversity. The approach used in this study was effective to explore the virome inside a pool of hypovirulent C. parasitica isolates. Next-generation sequencing allowed us to exclude the presence of any other ssRNA and dsRNA viruses infecting the fungus and determine CHV-1 as the only responsible of hypovirulence of C. parasitica in the analyzed samples
