What’s growing on my grass?

Asked July 6, 2020, 7:45 PM EDT

My son noticed a small patch of grass where clusters of reddish brown threads are growing on the blades. See attached photo. I’ve never seen this and was unable to identify it with my google searches. It seems significantly different than the red thread photos I saw. What is it? Do I need to treat it? And if so, how best? Thank you for helping me with this question! Kristin
