This is an example of a healthy Coffea arabica plant, the host of Colletotrichum kahawae.

Colletotrichum kahawae is a fungal plant pathogen that causes coffee berry disease (CBD) on Coffea arabica crops. The pathogen is an ascomycete that reproduces asexually. The asexual spores (conidia) are stored within acervuli.[1][2] This disease is considered to be one of the major factors hampering C.arabica production in the African continent, which represents the current geographic range of the fungus.[3] Coffee berry disease causes dark necrosis in spots and causes the green berries of the coffee to drop prematurely. High humidity, relatively warm temperatures, and high altitude are ideal for disease formation.[4] Given the severity of the disease and the lack of effective control measures, there is great concern that the fungus may spread to other coffee producing continents, such as South America, which could have catastrophic consequences.[5]
