Colletotrichum lindemuthianum is a fungus which causes anthracnose, or black spot disease, of the common bean plant (Phaseolus vulgaris). It is considered a hemibiotrophic pathogen because it spends part of its infection cycle as a biotroph, living off of the host but not harming it, and the other part as a necrotroph, killing and obtaining nutrients from the host tissues.
