Hard, Hollow 'Bubbles' in Lawn: Identifying and Treating Soil Fungus

What They Are

Firm, hollow, mushroom-like structures just under the surface are the fruiting bodies of a soil fungus. Most of the organism is underground.

Most are not toxic, but taste bad. Pets and kids rarely eat them. For positive ID, take a sample to your extension service.

Difficult. Treat with a soil fungicide like Consan 20 as often as label allows for a full growing season.
