03A7F100050FFFEAFF48F931CD2EFC37.taxon	diagnosis	Diagnosis: — Irpex jinshaensis is characterized by an annual growth habit, resupinate basidiocarps with white to cream pores when fresh becoming salmon to cinnamon upon drying, a monomitic hyphal system, generative hyphae thickwalled with simple septa, and occasionally covered with small crystal granules, the presence of encrusted cystidia and broadly subglobose to globose basidiospores. Etymology: — ‘ jinshaensis ’ (Lat.): refers to the valley of the Jinsha River, where the holotype was collected. Type: — CHINA. Yunnan Province, Shuifu County, Tongluoba Forest Park, on fallen angiosperm branch, 1 July 2021, Y. C. Dai, Dai 22402 (Holotype, BJFC). Description: — Basidioma annual, resupinate, cushion-shaped, closely adnate, soft corky when fresh, becoming hard corky upon drying, up to 8 cm long, 2.5 cm wide, and 0.25 mm thick; margin distinct, white, fimbriate, thinning out; pore surface white to cream when fresh, becoming salmon to cinnamon when dry; pores angular, 4 – 6 per mm; dissepiments thin, entire to slightly lacerate; subiculum very thin to almost absent; tubes concolorous with poroid surface, less than 1 mm long. Hyphal structure: — Hyphal system monomitic; generative hyphae thick-walled, simple septate; all hyphae IKI –, CB +, unchanged in KOH. Subiculum: — Generative hyphae hyaline, thick-walled, frequently branched, interwoven, often filled with oily contents, occasionally covered with small crystal granules, 3 – 5 μm in diam; oily materials scattered throughout the subiculum. Tubes: — Generative hyphae hyaline, thick-walled, often branched, interwoven, occasionally covered with small crystal granules, 2 – 4 μm in diam, narrower than those of subiculum; cystidia conspicuous, abundant, mostly as true thick-walled hymenial cystidia arising from basidial side branches, up to 43 µm long and 5 µm wide, cylindrical to conical, apically heavily incrusted, but also as generative hyphae emerging into the hymenium with an apical encrustation, arising deeply from the trama, the transitions between these two types or forms present, incrusted part 8 – 32 × 3 – 7 μm; basidia clavate, hyaline, thin-walled, bearing four sterigmata and a simple basal septum, flexuous, 16 – 18 × 4 – 5 μm; basidioles similar in shape to basidia, but slightly shorter. Basidiospores: — Subglobose to globose, hyaline, thin-walled, smooth, IKI –, CB –, 4 – 5 × 3.5 – 4 μm, L = 4.28 μm, W = 3.75 μm, Q = 1.14 (n = 60 / 1).	en	Tian, Xue-Mei, Man, Xiao-Wu, Liu, Zhan-Bo (2022): Irpex jinshaensis sp. nov. and I. subulatus comb. nov.

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. Dai, Dai 5929 (BJFC 010379, IFP 003711); Shanxi Province, Zhouzhi County, Taibaishan Nature Reserve, on fallen angiosperm trunk, 25 October 2006, H. S. 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).	en	Tian, Xue-Mei, Man, Xiao-Wu, Liu, Zhan-Bo (2022): Irpex jinshaensis sp. nov. and I. subulatus comb. nov.
