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.

2017년 독도의 버섯상 조사를 통해 관속식물인 왕호장근의 기부에 발생한 목재부후균 버섯표본을 수집하였다. 수집된 목재부후균은 배착성으로 자라는 가죽질의 자실체를 형성하였고 자실층은 관공형태를 나타내었다. 또한 균사체계는 위이균사형이며 타원형의 담자포자를 형성하였다. 형태적 특징과 균류바코드 영역 (internal transcribed spacer of rDNA) 분석을 통하여 이 버섯을 Xylodon flaviporus (Berk. & M.A. Curtis ex Cooke) Riebesehl & Langer로 동정하였다. 이 버섯은 독도에서 서식이 확인된 두 번째 종이며, 다년생 초본식물인 왕호장근을 X. flaviporus의 새로운 기주식물로 보고하고자한다.
