This disease poses a significant risk factor for forest health, potentially leading to economic losses for wood producers. To provide a genomic basis of the CC pathogenesis, the genomes of two &lt;i&gt;Cytospora&lt;/i&gt; species associated with the disease were sequenced and further analyzed within a set of Diaporthales species. The first species was identified as &lt;i&gt;C.piceae&lt;/i&gt;. The second was described as &lt;i&gt;C.piceicola&lt;/i&gt; &lt;b&gt;sp. nov.&lt;/b&gt; based on morphological characteristics and multi-gene phylogenetic analysis. The novel species is sister to other &lt;i&gt;Cytospora&lt;/i&gt; species isolated from conifers. Here, we report 39.7 and 43.8 Mb highly contiguous genome assemblies of &lt;i&gt;C.piceae&lt;/i&gt; EI-19(A) and &lt;i&gt;C.piceicola&lt;/i&gt; EI-20, respectively, obtained using Illumina sequencing technology. Despite notably different genome sizes, these species share the main genome characteristics, such as predicted gene number (10,862 and 10,742) and assembly completeness (97.6% and 98.1%). A wide range of genes encoding carbohydrate-active enzymes, secondary metabolite biosynthesis clusters, and secreted effectors were found. Multiple experimentally validated virulence genes were also identified in the studied species. The defined arsenals of enzymes and effectors generally relate to the hemibiotrophic lifestyle with a capability to switch to biotrophy. The obtained evidence also supports that &lt;i&gt;C.piceae&lt;/i&gt; EI-19(A) and &lt;i&gt;C.piceicola&lt;/i&gt; EI-20 can cause severe canker disease symptoms in &lt;i&gt;Picea&lt;/i&gt; spp. specifically. It was additionally observed that the strains of &lt;i&gt;C.piceae&lt;/i&gt; may have different pathogenicity and virulence characteristics based on the analyses of predicted secondary metabolite complements, effectomes, and virulence-related genes. Phylogenomic analysis and timetree estimations indicated that divergence of the studied species may have occurred relatively late, 11-10 million years ago. Compared to other members of Diaporthales, &lt;i&gt;C.piceae&lt;/i&gt; EI-19(A) and &lt;i&gt;C.piceicola&lt;/i&gt; EI-20 implied a moderate rate of gene contraction, but the latter experienced significant gene loss that can additionally support host specificity attributed to these species. But uncovered gene contraction events may point out potential lifestyle differentiation and host shift of the studied species. It was revealed that EI-19(A) and &lt;i&gt;C.piceicola&lt;/i&gt; EI-20 carry distinct secretomes and effectomes among Diaporthales species. This feature can indicate a species lifestyle and pathogenicity potential. These findings highlight potential targets for identification and/or detection of pathogenic &lt;i&gt;Cytospora&lt;/i&gt; in conifers. The introduced draft genome sequences of &lt;i&gt;C.piceae&lt;/i&gt; and &lt;i&gt;C.piceicola&lt;/i&gt; can be employed as tools to understand basic genetics and pathogenicity mechanisms of fungal species causing canker disease in woody plants.
