This species forms a granular thallus which, to the naked eye, appears little more than a coarse, black charcoal stain on soil or wood. Black, globose discs are usually abundant with a dark, purple-brown hypothecium (bottom layer of the disc) under the microscope. Spores: three-septate. C+ red or C-: all other reactions are negative. Wooden tree stumps, decaying timber, acid bark and peat. Northern Ireland, rare elsewhere.
