A stem blight of Bupleurum falcatum, characterized by blackish lesions, stem folding, wilt and blight of upper parts and lesions that bore acervuli with setae and pale-orange conidial masses, was found in Ibaraki Prefecture, Japan in 2020. The isolated fungus was identified as Colletotrichum chrysanthemi based on morphology and rDNA-ITS and β-tubulin-2 sequences and reproduced the original symptoms after inoculation of B. falcatum. We named the disease anthracnose (tanso-byo in Japanese).
