title: Irpex hydnoides, sp. nov. is new to science, based on morphological, cultural and molecular characters.
abstract: Irpex, one of the most common polypore genera, is easily identified by macro- and microscopic characters. During field trips to Korea's Kangwon Province, some Irpex specimens with conspicuous morphological differences from I. lacteus were collected. Cultural characters and molecular evidence differentiated this new strain from I. lacteus, and this taxon is proposed as I. hydnoides sp. nov.
