This disease attacks the crowns of plants, which is different than other anthracnose diseases. Anthracnose of turfgrass can be a foliar disease or in this case a basal rot of the lower portion of the plant. It attacks different species of turfgrass throughout the world most commonly annual bluegrass and creeping bentgrass (Crouch, Clarke 2012).
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.
A view of an infected pepper . Colletotrichum capsici has a broad host range but prefers peppers, yams and eggplants. On chili peppers, Capsicum annuum L., C. capsici infect the stem, fruit, and leaves of the plant, causing anthracnose, die-back and ripe fruit rot.
C. gloeosporioides has an extremely broad host range, causing anthracnose disease on a variety of crops such as cereals and grasses, legumes, fruits, vegetables, perennial crops, and trees. [citation needed] It has been observed as infecting harvested durian of the species Durio graveolens. [1]
The history of the Colletotrichum genus is a case study on the tension between the lumpers and splitters. [2] While the genus Colletotrichum was first proposed in 1831, [3] the exact definition of Colletotrichum and the species that belong in this genus has been in flux ever since. [4]
With poorly timed applications, there could be an increase of disease severity due to the disturbance of natural biocontrol mechanisms and increased crop susceptibility. [6] Pest control is also crucial in the containment of the disease. After rainfall or irrigation, anthracnose symptoms may occur.

It causes the disease anthracnose that can effect curcubits causing lesions on various parts of the plant. It can effect cucumbers, melon, squash, watermelon and pumpkin, especially when the weather is rainy, humid and warm. It can be transmitted by seed as well as soil and survive between crops.
