Over the last year and a half I have been getting these rings in my lawn...experimented with everything... aerating ....less water..... no fertilizing,...... more fertilization....thought is was something called ferry rings ....the weird part once it starts to go a way...then over time it starts getting bigger in diameter.
The one picture that looks like it is shaped like a heart is just luck of nature ...
I thought that also. however cannot find any definitive way of proving that, we used to have some really good plant nurseries here in Abq...but they have all closed ( ones left no Grey beards in the place) so no one local that knows are climate, which is very dry ...leading me to think it would not be fungi ...but obviously anything I have thought has not worked
A BIG FOOT NOTE.....it starts as a dead spot, then the center starts to grow green again and the circle starts to get bigger and bigger leaving the center to get greener and start looking like normal grass...that is the heart shaped spot...that is two years old ....

Call your local Agricultural Extension for advice. It IS a fungus and spreads in that pattern as the spores are released outward from the mature fungi. I'm not sure what to use to kill it...most drastic solution is to remove the sod and about 6 inches of dirt for at least 2 feet around the outside of the circle. Fill back in with sterilized dirt and re-sod or seed.
There are several ways to minimize damage to the grass in Fairy Rings. The grass should be fertilized with nitrogen several times a year to help mask symptoms. Most of the Fairy Ring growth (a fungal mat) is in the ground underneath the Fairy Rings, and this growth causes the soil to become nearly impervious to water. Using a "root feeder" attachment on a garden hose, punch holes at least every foot in the yellowing or dying area and pump large amounts of water into the ground to a depth of 10-24 inches. Repeat frequently. Increasing the soil moisture may also change the ecological balance enough to retard the growth of the Fairy Ring fungi. Application of a wetting agent to the area may also increase soil permeability and help to lessen symptoms. Aeration also reduces the symptom severity.
So this could be geographical ...(in this climate zone)

....interesting question, my house is at 5995 feet....NM has months on end we average 4% to a high of 20% humidity and that is the only time I see some mushrooms (damn little, like five a year)...only because we need to water so much to keep the the lawn green....and it never seems to correlate to the rings.
Tired all of this...maybe not that deep on the root feeder..... except the water wetter...hum....???...for lawns what in the world would that be? Used it in engines...
