AbstractHymenaea stigonocarpa, popularly known as ‘jatobá’ or ‘jatobá‐do‐cerrado’, is a native plant widely distributed across Brazilian Cerrado areas. This plant is used for urban afforestation, human and animal feeding, and industry. Foliar lesions resembling anthracnose symptoms were observed on H. stigonocarpa in natural habitats and nurseries. Microscopic examination of acervuli indicated a Colletotrichum species as the cause of the anthracnose symptoms. Based on multilocus phylogenetic analyses including data from APN2, APN2‐MAT/IGS, CAL, GAP2‐IGS, GAPDH, GS and TUB2 alongside morphological characterization and pathogenicity tests, Colletotrichum siamense was confidently identified as the causal agent of H. stignocarpa anthracnose in Brazil.
