This is a common fungal infection. There are many ways to get rid of this from boiling water, to peroxide and water mixed half and half, to wettable sulfur.

I recommend leaving it, however, as it can actually be good for your lawn! Just unsightly. It will clear itself up over time, and even help combat other infections in the yard.
