Brown spots on the papyrus fruit leaf
What is it

From indoor and outdoor gardeners alike, one of the most common gardening questions is, Why do my plants have spotted and brown leaves? And while there are many reasons for plain old brown spots, when those spots look like little brown bull’s-eyes, the answer my friends, is fairly simple , organism-wise that is. Those plant leaf spots are caused by one of nature’s most basic organisms: a fungus. Plants with Spotted Leaves Fungal leaf spot can be found in your outdoor garden as well as on your houseplant. Spotted leaves occur when fungal spores in the air find a warm, wet, plant surface to cling to. As soon as that microscopic spore gets comfortable in its new home, sporulation (the fungal method of reproduction) occurs and the tiny brown fungal leaf spot begins to grow. Soon the circle grows large enough to touch another circle and now the fungal leaf spot looks more like a blotch. Eventually the leaf turns brown and falls to the soil where the spores sit and wait for the next available warm, wet, plant surface so the fungal leaf spot process can begin again.
