If your lawn is developing irregular brown or yellowish patches and eventually dies,  it might well be infected with Anthracnose.

This fungal disease can occur in two forms, Basal rot, occurring during the cooler, wetter months of late Autumn / Winter, and Foliar blight, occurring during the warmer months of Summer when the warm weather is mixed with periods of intermittent rain. It can be particularly serious on annual meadow grass (Poa annua) but can also occur on both bents and fescues.

The fungus (Colletotrichum cereale) normally occurs when the grass is under stress, possibly as a result of low Nitrogen availability, high levels of compaction or very close mowing, and climatic conditions are suitable.
