Gewundene Kohlenbeere

Nemania serpens is a saprotrophic ascomycete fungus producing flat, black, crust-like stromata that creep along the surface of dead wood, particularly hardwood branches and logs. It is found across temperate forests in Europe and North America, where it plays a role in wood decomposition. This species is one of the more commonly encountered wood-inhabiting ascomycetes in deciduous woodland.
