Is this Fungus? If so, what can be done this late in the year?

I'm not sure what it is, but I believe you have company.





It's not limited to fescue. Here is some wild garlic getting in on the action.



I was hoping that it might be rust, but I couldn't stain a paper towel with a sample from an infected area.

Also, it seems to be worse after 12 hours of rain yesterday.

And I've noticed a similar outbreak on other fescue lawns in the area--including well-maintained lawns.

I'm not sure what else it could be other than a Fungus. We've been really warm, but we've been dry. So, I don't know. Interested to see what this cold weather does to it.

There are several yards in my neighborhood that have it as well.

That's been my assumption as well. I just don't know what kind of fungus. It is kind of strange that I am seeing it on so many lawns around the same time.
I don't plan to treat it. I'm just kind of pushing it out of my mind and hoping that the winter takes care of it.

Social port - I don't see anything concerning in your images.

Micahp - your images look a bit concerning. Is this in one area / patch or all over? I would look into brown patch. Try using this website to help to id the problem. http://turfdiseaseid.ncsu.edu/Default.aspx

Is the enviroment is right a fungus could in December too.

It's in a few areas. The picture I posted is along a sidewalk. The affected grass spans the entire length of the side walk. There are also a few areas in the main yard that are affectd.

My guess is that it is a fungus. Our temperatures have really fallen. We were in the mid/upper 60's on Tuesday(and were that warm for a few weeks). We don't get out of the 40's except fro one day in the next 7 -10 days. So, hopefully this will not expand any further.

Would it hurt to put out a fungicide?

I've got the same thing going on. I'm going to wait till this cold snap is over, and decide then what to do. Last thing i want is a fungus problem lingering around all winter.

Could it be that one cultivar is going dormant before the rest?
