There are two main types people usually mean when they say “mildew”:

  1. Powdery mildew
    • Very common on plant leaves (especially roses, cucumbers, grapes, zucchini, lilacs, etc.)
    • Looks like someone dusted white talcum powder or flour on the leaves
    • Does not usually kill the plant but weakens it
  2. Mold/mildew in homes (often just called “mildew”)
    • Thin, flat growth on bathroom tiles, shower curtains, windowsills, basement walls, leather, fabric, books, etc.
    • Usually white → gray → black as it grows older
    • Has a characteristic musty, damp, unpleasant smell

Quick comparison people often confuse:

Term Appearance Surface it grows on Smell Usually called
Mildew Thin, powdery or flat Plants / bathroom surfaces Mild musty Mildew
Black mold Thick, dark black/green Walls, drywall, wood Strong musty Mold

In everyday language, when people say “mildew” they usually mean the white/grayish thin fungal growth in damp household areas (especially bathrooms), while darker, thicker, more toxic growth is usually called “mold”.
