what is the difference between mold and fungus
Mildew can be described as a specific type of mold. Mold is a fungus that contains multiple identical nuclei and grows in the form of filaments or hyphae which penetrate beneath the surface of the affected material. Mildew, on the other hand, has flat growth that remains on the surface.
Fungi (singular fungus) are a kingdom of eukaryotic organisms. The fungi are heterotrophic organisms characterized by a chitinous cell wall, and in the majority of species, filamentous growth as multicellular hyphae forming a mycelium; some fungal species also grow as single cells.
