Stumbled across these black, finger-like
What Are They?
Black, finger-like growths in mulch are often Xylaria polymorpha,
commonly called Dead Man’s Fingers.
Despite their eerie look, they are harmless fungi that
help break down decaying wood and enrich the soil.
Appearance and Habitat
They grow three to four inches tall, starting pale before turning dark and woody.
These fungi usually emerge from buried wood,
stumps, or mulch in damp, shaded areas, especially during spring and fall.
Identification and Safety
Dead Man’s Fingers have a smooth, finger-like shape, a black outer
surface when mature, and a white interior if cut. They are sometimes confused
with other fungi, like stinkhorns, but can be identified by their structured growth.
They are not dangerous to people, pets, or plants and are considered inedible due to their tough texture.
Removal and Role
Removal is optional and mainly for appearance.
Pulling them out with the decaying
wood is enough. Reducing excess wood and improving drainage can limit regrowth.
Their presence highlights the important role fungi play in healthy ecosystems.
