B. Liu, X. M. Tian & Y. C. Dai 2022	<div><p>Irpex jinshaensis Z.B. Liu, X.M. Tian &amp; Y.C. Dai, sp. nov. (Figs. 2–3)</p><p>MycoBank no.—MB 841367</p><p>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.</p><p>Etymology:—‘ jinshaensis ’ (Lat.): refers to the valley of the Jinsha River, where the holotype was collected.</p><p>Type:— CHINA. Yunnan Province, Shuifu County, Tongluoba Forest Park , on fallen angiosperm branch, 1 July 2021, Y.C. Dai, Dai 22402 (Holotype, BJFC) .</p><p>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.</p><p>Hyphal structure:—Hyphal system monomitic; generative hyphae thick-walled, simple septate; all hyphae IKI–, CB+, unchanged in KOH.</p><p>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.</p><p>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.</p><p>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).</p></div>	https://treatment.plazi.org/id/03A7F100050FFFEAFF48F931CD2EFC37	Public Domain	No known copyright restrictions apply.

(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).</p></div>	https://treatment.plazi.org/id/03A7F100050DFFEBFF48FC72CDC0FDFA	Public Domain	No known copyright restrictions apply.
