What is a common characteristic of mold?

Fuzzy or powdery growths are a hallmark characteristic of mold. This can be observed as colorful patches or textures that develop on various surfaces, including wood, due to the growth of fungal spores. Mold thrives in damp environments, and its appearance is often the first indication of its presence, making this option not only identifiable but also relevant for recognizing mold issues before they escalate.

While mold does prefer humid conditions for growth, it can also survive in other environments, which contradicts the suggestion that it only grows in humidity. Furthermore, mold does not turn wood into dust; rather, it degrades the material through decomposition. Lastly, mold is not restricted to solid wood; it can grow on a variety of substrates, including porous materials and organic matter, which is why the characteristic of being found only in solid wood is misleading.
