What type of fungi reproduce by forming multicellular colonies?

Molds are a type of fungi that are known for reproducing by forming multicellular colonies. These colonies arise from the growth of hyphae, which are thread-like structures that spread out and form a mycelium. This mycelial network allows molds to cover large areas, which is why they can be seen as fuzzy or hairy patches on various substrates like food or damp surfaces.

Molds reproduce asexually through spores, which can be spread by air or water, and can germinate into new colonies under suitable conditions. This capability to form large, visible colonies and reproduce by spores differentiates molds from other types of fungi, such as yeasts, which are typically unicellular. The correct identification of molds in this context is essential for understanding their role in decomposition, food spoilage, and occasionally, disease in plants and animals.
