Remarks (public):Ceraceomerulius seems to have its closest relatives in the genus Ceraceomyces Jül. Thus we found it desirable to establish it as a genus of its own. While Byssomerulius subgen. Byssomerulius shows many features characteristic of Phanerochaete and similar genera, Byssomerulius sub.gen. Ceraceomerulius seems to have developed from athelioid fungi. Like Ceraceomyces it differs from Athelia preferably in the presence of a subhymenium. While in Athelia only a few basidia are produced from the hymenial hyphal branches, the basidial development in Ceraceomerulius and Ceraceomyces continues and results in a dense subhymenium with a more or less ceraceous consistency. This prolonged development of basidia gives the vertical subhymenial hyphae a characteristic sinuous appearance where sits of older basidia can be seen.
