Donadinia helvelloides

Urnula helvelloides is a species of fungus in the family Sarcosomataceae, first described in 1973 from southern France. The fungus forms distinctive cup-shaped fruit bodies measuring 2–2.5 centimetres in diameter, with a dark brown to black exterior and a black spore-bearing surface with a subtle reddish tinge, mounted on a slender stalk 3–5 centimetres long. It grows on dead yew branches partially buried in humus within mixed beech-yew-oak forests, fruiting between January and April at elevations of 650–700 metres....read more on Wikipedia.
