Grease Spot, better known as Pythium blight, can effect all grasses in humid climates and can be recognized by the slimy-brown patches that often have a white, cotton-like fungus around it. Grease Spot gets its name for the “greasy” appearance it makes while matting together and can appear in streaks across the lawn.
