Stumbled across these black, finger-like things poking out of the mulch in my backyard. They are hard and creepy. Does anyone know what this is?

considered edible, however, due to its tough texture and unappealing taste.
For plants, the presence of Dead Man’s Fingers is not detrimental as it primarily targets dead matter for decomposition. It does not parasitize living plants, making it a benign presence in your garden from a horticultural perspective.
