Maybe they are tiny red mushrooms.

Has it been overly wet where you are?

Not really. Eastern nebraska. Gets little rain. I water 4 times a week, otherwise, the harsh summer burns the grass

4x/week is waay too frequent. You are encouraging shallow root growth which can lead to heat stress and thatch. It also promotes weed growth. Search this forum for watering practices. If the soil were allowed to dry out completely on the surface you probably wouldn't get those red mushroom looking things. You should be watering deep and infrequent, like probably max 1/week, and more typically every two or three weeks, barring rain.

Edit to say that infrequent watering and cutting grass as high as the mower will allow will promote deep roots which will withstand the heat stress more easily.
