Mushrooms in Ficus Soil: Fungal Bloom from Organic Matter

What They Are

Lepiota lutea (yellow houseplant mushroom) — fruiting body of fungus decomposing organic matter in potting soil. Spores everywhere.

Are They Harmful?

• To plant: usually not.
• To pets/kids: potentially toxic if eaten. Remove.

Cultural Fixes (Discourage Fungus)

• More light for ficus (bright indirect + some direct).
• Drier soil — let top 1–2 inches dry between waterings.
• Raise pH: Light lime top-dressing; avoid coffee grounds.
• Sandier mix next repot.

If Persists

Repot in fresh, sterile mix. Wash roots. Clean pot with bleach solution.
