<i>Diaporthe mahothocarpus</i> GZU-Y2, a new pathogen responsible for leaf spot blight disease, leads to significant damage and economic losses in some <i>Camellia oleifera</i> plantations. The current study annotated the genome of the <i>D. mahothocarpus</i> isolate GZU-Y2 to advance our knowledge of the pathogen and facilitate improved disease management of leaf spot blight. The initial Pacbio-Illumina hybrid draft genome for GZU-Y2 resulted in a high-quality assembly with 62 contigs, characterized by an N50 length of 7.07 Mb. The complete genome of isolate GZU-Y2 was 58.97 Mbp, with a GC content of 50.65%. Importantly, the assembly exhibits remarkable integrity, with 97.93% of complete BUSCO validating genome completeness. The prediction results showed that a total of 15,918 protein-coding genes were annotated using multiple bioinformatics databases. The genome assembly and annotation resource reported here will be useful for the further study of fungal infection mechanisms and pathogen–host interaction.
