Molds (e.g., Aspergillus, Penicillium, Cladosporium)

Molds like Aspergillus, Penicillium, and Cladosporium are types of fungi that grow in the form of multicellular filaments called hyphae. They thrive in damp, warm environments and often appear as fuzzy or colored patches on surfaces such as food, walls, or plants. Molds are important in nature for breaking down organic material, but indoors, they can cause health issues like allergies or respiratory problems. Some molds, like Penicillium, are used to produce medicines (e.g., antibiotics), while others can produce allergens or potentially toxic compounds, so controlling moisture is key to preventing mold growth indoors.
