They could be growing on rotting dead wood underground, eg on the roots of a dead/removed tree in which case they will go of their own accord when the wood is all rotted. Or more likely they are a grassland species that grows in rings.

In general there is no reliable way of getting rid of them. But if you approach lawn care with a a less organic, more interventionary, way with regular application of feeds and weedkillers, and scarifying and aerating and so forth, then such lawns are less likely to get fungi growing on them.

But they don't do much harm to the lawn, and most of us just delight in them.
