Recognisable by its woolly or cottony colonies that start greyish-white to olive and darken with age. C. globosum degrades cellulose-based materials (e.g. paper, drywall) in conditions of sustained moisture. When disturbed, it can release spores that degrade indoor air quality. Identifying hidden leaks, improving ventilation, and removing contaminated materials (if extensive) are essential steps for long-term control.
