Despite the common names ringworm and dermatophyte, the disease is caused by a fungus, not a worm or plant. Trichophyton, Microsporum, and Epidermophyton are the most common genera that cause ringworm in humans. These organisms feed on keratin, the major structural component of hair, skin and nails.

I have a Kentucky Bluegraa lawn, laid ontop of some very clay-like soil. I have had success with my lawn, but the last two years i have gotten some white patches on my lawn. They totally kill the grass, and there is a white powder substance in it. it looks like alkali, and the grass looks bleached.rass which is affected may turn yellow and die as the white powder covers the green leaves and prevent the grass from photosynthesizing. You can test for this by rubbing a piece of grass blade between your fingers. If the white powder rubs off on top your hands then it is PM.
