s. This fungus causes the disease commonly known as American Leaf Spot. ''Mycena citricolor'' affects coffee plants, primarily in Latin America, but can grow on other plants as well.
This fungus can grow on all parts of the coffee plant including the leaves, stems and fruits. When grown on the leaves, ''Mycena citricolor'' results in leaves with holes that often fall from the plant.
Description
The ''Mycena'' fungus can be identified growing on somewhat circular, brown spots on coffee leaves. The brown spots are caused by the presence of the parasitic fungus and by looking at the leaves closely, small mushrooms with
