This stipitate polypore is unusual in that it produces pileate basidiomata. The hymenophore can be poroid or hydnoid. It occurs on dead wood of hardwoods and conifers in Europe and in North America where it causes a white rot. The fungus was just discovered for the first time in Central America under thickets of Comarostaphylis arbutoides in the páramo of the Talamancas. This fungus was kindly identified by Dr. L. Ryvarden who places it in the Corticiaceae.
