    I have looked all over for something that describes this crap that keeps popping back up on fescue that I cut. It has been VERY humid and moist here in Alabama lately. I have seen a lot of brown patch around here lately, but I don't know what this is. I applied Bayleton a few weeks ago, but I even have the brown patch coming back! Sheesh...

    I was thinking maybe slime mold? It seems to turn black after a day or two. I have never had a problem with slime mold before, so I have never personally seen it.

    I agree it looks like powdery mildew. It comes from all these afternoon showers we've had. I've never had any problems with it doing damage to the grass. I wouldnt sweat it.

    YEs, that is slime mold, not uncommon with very high humidity and high temps through the evening and nighttime hours. ITs typically a cosmetic situation, i've never seen where it has done any permanent damage to turfgrass except to slightly stress where its heavily inflicted. Most mowing will remove a majority of the mold and sometimes even using a shop broom to brush the spores off will hinder their appearance.
