Fumagine

/ˈfjuː.mə.dʒiːn/ noun

Definition

A black sooty substance produced by certain fungi and insects on plants, particularly a deposit that accumulates on leaves and stems.

Etymology

From French 'fumagine,' derived from Latin 'fumus' (smoke) with the suffix '-ine.' The substance resembles soot or smoke deposits on plant surfaces.

Kelly Says

Sooty mold (fumagine) is created by fungi feeding on honeydew left by aphids—it's a perfect example of how nature's troubles pile up: bugs poop, fungi eat it, and suddenly your plant is covered in black dust.
