CHARACTERISTICS
Mushrooms often appear in lawns during periods of warm, wet weather. Fairy rings are semi-circular rings of dark-green grass in turf, often accompanied by mushrooms. Turf within the rings will turn yellow and appear dead.
Fairy rings and mushrooms usually appear in soils that contain decomposing organic material. Tree roots, sawdust, or bark mulch can be sources.

PREVENTION AND CONTROL
• Apply adequate nitrogen to soil. Mushroom rings and other similar problems are often related to soil infertility and imbalance of the microbial activity in soil.
• Aerate the affected area to ensure better water penetration, then water heavily. Mushrooms can be raked off and removed.
