Colletotrichum higginsianum is a fungal pathogen that infects Brassicaceae plants like cabbage, and Arabidopsis, causing anthracnose disease with dark, sunken lesions on leaves, stems, and fruits.

Not a host
COLLHG-9, COLLHG-10, COLLHG-11
Mustard has been cited as a host based on COLLHG-9; however, this publication does not confirm such a claim, and Brassica juncea has only shown symptoms under artificial inoculation. Therefore, it does not meet the ISPM 5 definition of a host.
