I am located in the chicago suburbs with kentucky bluegrass (sorry for the typo) as the grass type. We had a mild winter and am wondering if the attached (brown patches) are fungus. I noticied it spread compared to last year. Thank you.

    Is the white stuff on the left residual snow? Just wondering cos you said your winter was unusually mild... otherwise, for diagnostic purposes, clear close up photos of the brown patches is necessary. – Bamboo Mar 2 at 13:29
  • Added a close up, we had inches this year and temps above 30 mostly. Usually we get several feet with negative temps. Thank you. – justaguy Mar 2 at 15:19
