I wouldn't recommend it, but I'm sure as a child I've eaten leaf mold before. I wouldn't recall what it tastes like, but I'm sure I've tasted worse having grown up on a small farm. Heck, we used to pull up carrots straight out of the field and rub most of the dirt off on our jeans before munching it straight down, radishes too. Once as a kid I accidentally ate cow paddys, or at least tasted them. I was bareback riding our horse "Shylow" and galloping down a hill in the pasture when she stopped suddenly and put her head down. I must have slid a good 20 feet on my belly with my mouth not fully closed. I was picking pieces of cow paddy out of my mouth. That was bad.
