How do I get rid of Todstools in my lawn

Toadstools and other fungi are feeding on organic matter below the soil, so even if you used a fungicide, they'd come back. As Bamboo says, they will disappear when the lawn dries out. Improving drainage would help them from reappearing.

You don't - you can twist them off if you don't like the look of them and discard, but they'll disappear on their own in a couple of weeks or so.
