I think the questions you're really asking are 1) are mushrooms on the lawn harmful (no) and 2) how can I tell if I'm watering the lawn correctly. The answer to the second question is best obtained with a soil probe or a spade. Take a 12" deep slice of lawn and take a look at it: are the grass roots down to at least 6"? Is the soil damp 6-12" down? If so, you're doing things right. If your grasses have shallow roots, or if the soil isn't damp at least to 6" a couple of hours after watering, you are applying too little water too often.
