Mushrooms can be a good sign of good bacteria in the soil, breaking down organic matter, and making nutrients available for your lawn. You just want to keep them working down in the soil, and not popping their heads up to look around. If you see mushrooms in your lawn, it means your grass canopy has been too wet for too long. You see it often in the spring when there's several rainy days in a row. Not much you can do about that, but if it hasn't been raining, and you see mushrooms, your sprinklers are watering too frequently. You need to give the grass a good watering, then let it dry all the way out.
