Dollar Spot Fungus: The Likely Cause of Small Dead Spots with Soil Bumps

Symptoms Match

50–60 small dead spots, each with a tiny soil bump, bald soil center. Wet summer. Tiny worm found (likely benign). Classic dollar spot (Sclerotinia homoeocarpa)—a mild fungal disease from excess moisture.

Why Not the Worm

Earthworms don't kill grass in spots. They improve soil.

Management

• Reduce watering frequency; water deeply early morning.
• Apply organic nitrogen (Milorganite, compost).
• Mow high, sharp blade.
• Fungicide rarely needed; cultural fixes work.
