An ML tree showing phylogenomic relationships of C. piceae EI-19(A), C. piceicola EI-20, and other species of Diaporthales. Bootstrap support for all clades is 100. Blue and red numbers on nodes indicate the number of expanded and contracted gene families, respectively. Circles represent the number of expanded and contracted gene families for the top eight COG categories. Abbreviations: Q—Quaternary, N—Neogene, PG—Paleogene, K—Cretaceous, MYA—Million Years Ago.
