"Mold" is the common term for multicellular fungi that grow as a mat of intertwined microscopic filaments (hyphae). Molds are pervasive in the outdoor environment but may also be present indoors under certain conditions, primarily in the presence of excessive moisture from leaks in roofs or walls, plant pots, or pet urine. The most common indoor molds are Cladosporium, Penicillium, Aspergillus, and Alternaria. Other molds that can grow indoors include Fusarium, Trichoderma, and Stachybotrys; the presence of these molds often indicates a long-standing problem with water leakage or damage.
