Help to identify the enclosed...

I know it's difficult to identify a fungicide problem from just a photo... And I do need to have the soil tested... But a quick identification would be helpful...

Red thread? Look at the grass closely and see if it looks red.

I am leaning toward dollarspot. The top inch of the leaf blade tends to be creamy white. Warm humid conditions. Spots about 4 to 6 inches in diameter--bigger on tall turf--smaller on short-cut turf.
Red thread is easy to identify--just look for the red threads at the tips of affected grass blades.
Rust is easy to identify--distinct tiny football shaped spots--yellow dust and--it is mainly a fall disease.
