Abstract

In 2017, we collected a wood-decay fungus growing on a dead and decaying herbaceous plant (Reynoutria sachalinensis (F. Schmidt) Nakai) in Dokdo, the far-eastern island of South Korea. Morphologically, this species is characterized by resupinate, coriaceous to corky basidiocarps, poroid hymenophores, pseudodimitic hyphal system, and ellipsoid basidiospores. Based on morphological observation and internal transcribed spacer of ribosomal DNA, the fungus was identified as Xylodon flaviporus (Berk. & M.A. Curtis ex Cooke) Riebesehl & Langer. It is only the second macrofungal species reported from Dokdo, and R. sachalinensis is the first herbaceous plant to be identified as a host for X. flaviporus
