Found in soil, decaying wood, and water-damaged wallpaper. Notable for its ability to produce arsine gas.
Scopulariopsis colonies are typically tan, light brown, or buff-colored with a powdery or granular texture. They grow at a moderate rate and develop a characteristic rough surface. Under a microscope, its spores are round to lemon-shaped with a rough, spiny surface.
Scopulariopsis is found in soil, decaying plant material, and various indoor environments. It commonly grows on damp wallpaper, painted surfaces, and wood. Historically, it gained notoriety for growing on arsenic-based wallpaper pigments in Victorian-era homes.
Scopulariopsis can cause allergic reactions and respiratory irritation. It is an occasional cause of nail infections (onychomycosis) and can cause more serious infections in immunocompromised individuals. Notably, when growing on materials containing arsenic compounds, it can convert arsenic into toxic arsine gas.
Scopulariopsis is commonly found on water-damaged wallpaper, painted surfaces, and drywall. It tends to appear after prolonged moisture exposure and is often found alongside other mold species. Its presence indicates a sustained moisture problem that needs to be addressed at the source.
