Daldinia concentrica is a type of fungus commonly known as the black finger fungus. It typically grows on decaying wood, particularly in temperate forests. This fungus is characterized by its dark, round fruiting bodies that can resemble small, black balls or fingers. The fruiting bodies of Daldinia concentrica are often found in clusters and can be identified by their concentric rings, which give them a unique appearance. This species plays a role in the ecosystem by breaking down dead wood, contributing to nutrient cycling in the forest environment.
