Ever wonder about mushrooms that seem to come up from no where in your lawn?  Here is some insightful information that may help you.

The mushrooms are growing on decomposing wood in his soil. There really isn't much that he can do until the wood finishes breaking down, unless he wants to dig up the lawn looking for the source.  He should just bear with it while the process takes its course.

The source of most mushrooms is decaying wood under the surface of the soil. Fairy rings which produce the marvelous circles come from wood as much as twenty-plus feet down. Circumstances have to be just right for the spores to produce mushrooms. There is no "cure". There is no chemical or non-chemical method to stop an attack of mushrooms as nothing can be used on the soil that will be effective after a few inches. Sure you could hire a backhoe and start digging until you find the offending piece of wood.  (Use the hole for a very deep in-ground pool!)

Mushrooms in a lawn is a sign of lawn health (unless you have truffles, then the lawn may die above them). If you don't like them in the lawn, pull them out and add to the compost pile.

I would suggest to him that it isn't really all that bad a thing, except of course if you tried to eat them. Of course a lawn purist is not going to like it but perhaps a change in attitude towards lawn is needed.

In case you can't tell, I dislike pure grass lawns and would welcome the mushrooms, wildflowers and anything less boring then a pure grass lawn.

In previous posts I haven't noticed anyone say anything about nearby trees. Thousands of fungi are mycorrhizal, and symbiotic with other plants. Some are even symbiotic with grass. Having these fungi is, as Martha Stewart would extoll, "a good thing."

And not all of them are poisonous. Why not find out what kind of fungi it is? You could have a ball doing it.

I'm reminded by a woman who came in to the Portland chapter of the North American Truffling Society several years ago. She was complaining that the mushrooms in her front yard were causing a mess and clogging up her lawnmower. After looking at the mushroom, I suggested she eat them. Worst case of morel lawn I ever saw! She probably had hundreds of them under her cottonwoods. All of which points out that not ever mushroom in a lawn is such a bad thing.
