The image shows a close up of a green leaf with a hole in it, which is covered in a layer of downy mildew. The mildew is a light brown color and is spread across the leaf, covering the entire surface of the leaf. The hole in the center of the hole is slightly larger than the surrounding area, and is surrounded by a thin layer of the mildew, giving the leaf a glossy sheen.
