Can someone please tell me what may be leaving/making a strange white "dust" in a shaded portion of my yard. I just moved back to the U.S. from overseas, and have never seen anything like this before. I just moved to Maryland and have noticed that there is an area in my yard that looks as if someone has "dusted" the grass with some sort of powder. It is white in color and scatters like dust when I shift it with my boots.
Thanks in advance, Hawkeye
