Based on specimens coming mostly from Central Europe, the group of species closely related to Hypoxylon serpens (Pers.: Fr.) J. Kickx fil. is newly classified with emphasis on microscopic characters. The Hypoxylon serpens-complex is separated from Hypoxylon Bull. and classified as a genus of its own, Nemania S. F. Gray in a considerably changed circumscription. Eight species are newly transferred to Nemania. One species is described as new: Nemania carbonacea Pouz. spec. nov. and the problem of N. atropurpurea (Fr.) Pouz. is discussed in detail.
