Answer: The mushrooms are growing because of decomposing organic debris. Could be compost or even dead roots in your lawn. Whatever the underlying cause, as soon as your soil dries out, the mushrooms will stop popping up. I'd just rake them out and dispose of them. There's really nothing on the market to kill them so raking or even handpicking are your best options - or mowing and bagging the clippings. Hope it stops raining!
