Black Fungus on Leaves (Sooty Mold)
Leaves have a spotty, black fungus on them. This is Sooty Mold, a fungus which finds a host on the honeydew left by certain insects. When present, Sooty Mold appears as tiny, dark speckles which cover the upperside of the leaves.
Sooty Mold may indicate the presence of a number of insect pests. You may either view the full list of possible causes, or select from the list of additional symptoms in order to narrow down your search.
