Without pics, I'll guess Summer Patch. Check out Purdue University.

It is fall. My vote goes to rust fungus. Do you get an orange dust when you walk through it? Very common in fall on various cultivars of ryegrass, and a few types of bluegrass. The grass gets a very yellow color. Fertilizer helps. Rust disappears about the time of frost.
