Irpicaceae has both polypore and crust fungi. They have a monomitic hyphal system, containing only generative hyphae that do not have clamp connections. Their spores are thin-walled, smooth, and translucent. Cystidia are often absent from the hymenium. More rarely, some species are dimitic and/or with cystidia and/or clamp-connections present; for example, Emmia and Irpex have cystidia, and there are clamp connections in Gloeoporus. Irpicaceae fungi produce a white-rot, except for one brown-rot genus (Leptoporus).[3]
