Macabre-looking clusters of hard, swollen, warty ‘fingers’, 3–8cm high. When young they are pale grey with a whitish tip. The pale covering is a coating of asexual spores produced in the early stage of their development. Inside, the flesh is white and tough under the black spore-bearing outer layer. Fruiting bodies: finger-shaped, grey or brown, blackening with age, varying from 1–3cm. Gills/spores: the spores are dark brown when developed, banana-shaped with a black spore print. Stipe: a small stalk which attaches the fruiting ‘finger’ to the dead wood.
