    Over the last week, I have noticed a large brown ring, about 12 feet in diameter and about 1 foot wide, forming in my grass (see attached photo). I think it may be a fungus, but not quite sure. I've applied fertizer regularly according to the Scott's plan. Any advice on what this is and how to treat?

    what is that pipe that is in line with the ring? could there be something underground that is causing it?

    That is something buried in your lawn's soil. I've never seen a fungus that perfectly round.

    I'll bet it has something to do with that pipe sticking up too.

    I'm thinking it's a cesspool that's leaching......

    That's a sewer vent, but we're on a public sewer system; no septic system. We've lived here two years and we've never had a problem. I've got a similar half moon circle starting in my back yard, which is nowhere near a sewer vent.

    My first thought was "fairy ring". Get a core sample. If you have funny white stuff in it, it's a fungus.
