No it's exactly like it looks thinned out and almost looks like dog pee or fertilizer type burn which I have not fertilized since april, so...Idk what it ..the rest of the lawn is pretty normal a few of those brown type spots but not bad...NO clue...it's annoying when this happens and you have NO clue, I been watering at 5pm-6ish it's the only time I can really w out going into the late night. which is bad.

Can you post a close up picture of the spots? Include some of the green grass on the edges.

How often and for how long do you water?

Sometimes I get rabbits camping in my lawn overnight & they leave a spot like that. They just chew on the grass & pee all over themselves which kills the grass, then move 2 feet over to do it again. Do you see any poop pellets around the edges?

Hmmm Ok I will post a pic later Thank you so much ;)

Very important question: How long and how often do you water?

I think Lisa likes to pop in from time to time. :o)

Lisa please remember the dchall recommendation on taking photos. Get 3 or 4 inches away from the grass and take pics on a cloudy day, or not in direct sunlight.

LOL at thought of bunnies peeing all over themselves.

Looks fungal from far away to me but would help to have a closer pic of the blades and some info on how much rain/irrigation.

+1 on the closeups. Could be fungal, could be dry spots, could be animal damage.

One other test to do is to stick a long-handled screwdriver (flat-blade works best) into the soil at those spots. Do you feel a rock underneath the soil, less than four inches down? Bingo, problem solved.

The rabbit damage is easy to diagnose by the presence of poop pellets. If there's no pellets, it's not rabbit damage.

it hasn't gotten any worse so Idk I water everyday for 30 mins around 5pm Its the ONLY time I have to water so when the sun is going off my lawn Is when I start before night night time, I am going to invest in watering system this fall I think but they will have to dig up my lawn won't they? its a small lawn though the front yard that is. Thank you all. will take more pics after I mow it thursday :)

well based on that, probably fungus...you are watering way too often, leading to shallow roots and prime conditions for fungus (wet and hot). you need to water less often and deeper amounts. goal is to get to watering just once per week with 1" all at once. it will take a while to train your roots to grow deeper. first thing to do is spread cans around the yard and see how long you have to run your sprinklers to get to 1" of depth. could be a long time. i have a zone in my yard that runs 2 hours, another 45 minutes. then you just watch your grass, when it starts to show stress from lack of water, you run the full 1". then you wait again until it shows stress. over time the gap between watering will be longer and longer. Once a week during summer, then every 2 weeks when the heat breaks. the way you are watering your lawn right now is bad for your lawn.

fungus? it hasn't spread though, its only in a few spots. here and there and not really that noticeable just to me because I am a fanatic with my lawn ;x

@lisa pretty much everybody here is a fanatic about their lawn. Those spots could be nothing, or they could be a sign of problems to come. If you take that very close up pic in the shade near the edges of the brown spot you'll know if it is fungal.

what do you mean in the shade, I don't have shade there till like 8:30 at night :x around...I am in Pittsburgh, so what do you want me to do? I am confused you want me to take it when the sun is off it???

OK I did it!! I went out there and perfect timing the sun went IN LOL ;)
so here they are and One other small spot on the other side of the lawn
which is small and I took the dead out of it and these a little bit I brushed it out w my fingers ...

should I dig it out and put Sod? Lol I Love sod, Obsessed to say the least!! my whole lawn was sodded back in Oct of 2009

Is this KBG grass? No need to do anything if so as it spreads quickly. Otherwise maybe wait till fall to spot seed as needed. Could just be some stray animal pee. Your photos, while great in the shade, are still a good 12" too far away. You need to get maybe 4" away from the blades at the edge of the brown spot. Having said that, I copied and enlarged your image. I see some yellowing from the tip down about a half inch on several of the blades at the border, but nothing like pics of fungus I've seen online (please be aware I don't know much about fungus ID). Most of the grass just beyond the edge of the brown patch looks very healthy with no sign of fungus as much as my untrained eye from too far away can tell, so maybe it is an isolated incident.

I would just keep an eye on it, but you seriously need to do something about your watering schedule.

Thank you so much!!!! Yes the Grass is Very Very Thick and Green, I was going to put some Milogranite sp? down wed night its going to rain hard here thursday! what do you think? And Yes its KBG, RYE and FESCUE I believe, I got it from the sod farm back in 2009 October to be exact. Thank you so much, I am so worried about it all the time It's a full time Job maintaining it and all the damn flowers and ornamentals shrubs I have

"damn flowers" lol. Well with KBG in the mix it'll fill itself back in. I guess there's never a bad time to use milorganite, but if you live somewhere that is very warm it might not need the feeding. Also, if you do have a tendency toward fungus because you are watering every day, then providing additional nitrogen is not a great idea, apparently. It gives the fungus more grass to feed on.

Thank you danielj :) I was going to spread some down, not a lot since it's going to rain hard here thur most of the day, I haven't fertilized at all since Late april, so I don't think it will hurt, Idk, it's pretty green though..mull it over Lol ughhh summer is awesome but the stress of keeping your lawn nice is too much at times esp when You have OCD like I do, my family thinks I am crazy Lol :(

@lisa my wife has OCD as well, but she manages to keep it compartmentalized so it doesn't make her crazy! I don't know if she really has OCD clinically speaking, but I've learned not to argue with her. Happy wife, happy life and all that!
