Can someone help me identify this? Is it s a fungus or a weed? I've Googled so much, but can't concretely determine what it is. I don't see the cobwebs that many fungus have, but it does sort of look fuzzy or like my grass blades have grass poms at the ends. Any help would be much appreciated! Thanks!

To me it looks like a patch of Nimblewill that has taken a nosedive due to the temps dropping. I'm sure the cool-season brethren will be able to offer you more insight.

I think you are on to something. I kept looking at pictures of nimblewill that was thriving, whereas, this does seem dormant. Thank you...this is a good starting point for me.

If anyone else can weigh in, that would be great!

I noticed leaves and long looking fine fescues. I would keep mowing and mulching those leaves. I would target 2.5in hoc.

Yeah, I'm definitely fighting the leaf war. Due for another mow, and will plan to lower the height. Thanks for the advice!!

That looks like either nimblewill or bentgrass.

Both are treatable by tenacity. This study found that:

Based on the results of this study, Tenacity should be applied at 1.0 oz per acre in each of three sequential applications on two-week intervals using a non-ionic surfactant plus UAN with power raking. Power raking will remove debris before each Tenacity application and allow for the greatest control of creeping bentgrass.

Don't worry about the UAN (basically just urea and ammonium nitrate dissolved) - most people don't do that and still get good results. Although the study did find an improvement using it.

Excellent! I have Tenacity and actually did use some of that on it already as I did a Pre-Em treatment with Dimension earlier this week. So I'll just keep treating it accordingly.

As for the UAN part, I am doing a weekly Urea feeding, so based on this, I should be good, right?

I believe the idea is adding fert (UAN) to the tank encourages the target weed to grow, which causes the herbicide to cycle through it more quickly. Given that, I assume what you're doing should work fine.
