Rust-Colored "Mushrooms" in Shady Lawn: Spores, Not a Threat

Peggy in South Texas has 4-inch woody brown growths in a shady, grassless spot. They release orange dust when knocked over, then regrow.

They're Mushrooms

The orange dust is billions of spores. It's a wood-decay fungus fruiting on buried organic matter (old roots, stumps).

Control If Desired

• Kick them over before spores mature (when still firm).
• Lawn fungicide will suppress but requires repeat apps.
• They don't harm grass—they just indicate decaying wood below.

Simple fix: Kick 'em. No chemicals needed.
