It can be recognized by more or less round, but many times also confluent and irregular shape, (almost) black spots on rotting trunks and fallen branches of Fagus sylvatica. Spots are flat, not cushion like. Ostioles are rather small. Ref.: (1) J. Breitenbach, F. Kraenzlin, Eds., Fungi of Switzerland, Vol.1. Verlag Mykologia (1984), p 270. (2) R.
