every year i get this same problem at this house, same EXACT spot and shape.
there is a big tree that drops acorns there but they fall over a big portion of the front yard and only that area has the problem.ive reseeded every year and every year when it gets hot(end of june early july) same thing.
the only thing i can think of is there may be something underground like a pipe or rock that is close to the surface not allowing for a good root system and when it gets hot c ya.
any ideas?

I'm guessing tree roots are the main cause.

Dig it up and see. Everyone likes to dig! :blob4:

Either something added TO the soil (spilled or dumped on) or something or something IN the soil like roots or foreign material.

Take a soil sample to the co-operative extension service for soil analysis

Pythium?

Do you turn the mower there? Some times the mower will drop wet grass clumps and will cause spots like this.

i know what it is...I think!!!!

Some trees actually drop a sappy type chemical and it can actually kill the grass....

can anybody back that up of is that totally left feild... im almost positive ive read that somewhere...

It doesnt look burnt, nor does it look like a fungus...

Probe it with a shovel, I agree could be tree roots. Many builders are also guilty of buring cement and other crap in lawns.

Can you ID the tree? You say their acorns which I assume then its an Oak, usually their root systems are deeper. Now if its a cherry, the pits will collect and I've seen where they'll burn a complete area from the acid from the pits then the areas will recoup fall thru the next spring. Check the leave tissue on the grass blades too, the pics look like they're black but can't tell. Good thing to do is tap a rod or piece of rebar in the ground to about a two foot depth, if you meet something on the way down you may have found your culprit, and its easier than digging to find nothing. I had a similar spot in a customers lawn that showed each year and especially when it got dry out, tapped a rod into the ground and hit something. Went ahead and dug it up to find the builders piled the leftover shingles there , easier than paying to have them hauled away i guess.
