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?

2. Meet Dead Man’s Fingers: The Fungus Lurking in Your Mulch
Dead Man’s Fingers, scientifically known as Xylaria polymorpha, is a saprobic fungus, meaning it feeds on decaying organic matter. This fungus is commonly found in deciduous forests but can also appear in garden settings, particularly where there is an abundance of wood chips or decomposing wood.
This fungus is part of the Xylariaceae family and is primarily responsible for breaking down cellulose and lignin in dead wood, playing a crucial role in nutrient cycling within ecosystems. The fruiting bodies often emerge in clusters, resembling a hand with multiple fingers, which adds to the eerie imagery associated with them.
