Strange Fungus in Antique Furniture: Identification and Safety

A furniture restorer discovered an unusual, tough fungus growing inside an old oak wardrobe that had been stored in a damp shed. The growth was so dense it prevented a drawer from opening, requiring a saw to cut through it. The owner is concerned about potential danger and how to treat it.

Expert Advice: Fungal identification requires examining microscopic structures, and species vary by region. Because this fungus is growing on wood indoors, it could indicate a moisture problem. Contact your local health department, a pest control company, or a mycologist for proper identification. Take clear photos and, if possible, a sample to a professional who can assess whether it poses a health risk and recommend remediation steps. Do not attempt to handle it extensively without knowing the species.
