Mushroom type and prevention
I have mushrooms in my yard and the local garden shop says there's nothing I can do to prevent them, only pick them as they appear. They grow low to the ground in clusters, in the shade of an ash tree. I have been at this address for 15 years, and this has only happened the last two years. What type are they, and do you have any recommendations for control or elimination?

I can't identify the mushroom in the photo. However, the individual at the garden center is correct. There is nothing that can be applied to the ground that will prevent them from coming up. If you find them objectionable, your only option is to pick and discard them when they appear.
