Cangwat Lamphum , Doi Inthanond , 20 February 1979 , Ryvarden 17843 Description: See Hjortstam & Ryvarden (1982 , as Oxyporus subulatus ). Specimens examined: CHINA . Henan Province , Xiuwu County , Yuntaishan , on fallen angiosperm trunk, 4 September 2009 , B . K . Cui , Cui 7275 ( BJFC 005762 ); Hubei Province , Shennongjia , Muyu , on fallen trunk of Celtis , 25 September 2004 , Y . C .

Yuan , Yuan 2733 ( BJFC 001406 , IFP 003703 ); THAILAND . Chiang Mai , on fallen angiosperm trunk, 24 July 2016 , Y . C . Dai , Dai 16719 ( BJFC 022826 ) . Notes: Simmons et al . (2016) described Flavodon ambrosius as a new species. In fact, we found that its description fits Oxyporus subulatus well, and its holotype (Hulcr 6853) sequences of ITS and LSU ( ITS : KR 119072 ; LSU : KR 119075 ) are almost the same as those from Oxyporus subulatus . Wu et al . (2017) transferred Oxyporus subulatus to Flavodon based on the results of the phylogenetic analyses. Herein, we place this species in Irpex based on morphological and phylogenetic evidence ( Fig. 1 ).
