Question: what is the difference between fungus and mould?
Answer: A mold (US) or mould (UK / NZ / AU / ZA / IN / CA / IE) is a fungus that grows in the form of multicellular filaments called hyphae. In contrast, fungi that can adopt a single-celled growth habit are called yeasts. ... The mode of formation and shape of these spores is traditionally used to classify molds.
