C8173C27FFC3FFD6FF6834B8FB60FB8C.taxon	diagnosis	Diagnosis. — The new species is characterized by perennial and pileate basidiomata, circular and small pores (7 – 9 per mm), presence of hooked hymenial setae, and ovoid to broadly ellipsoid, colorless, fairly thick-walled, weakly dextrinoid and moderately cyanophilous basidiospores. Type. — Vietnam. Lam Dong Province, Da Lat City, Bidoup Nuiba National Park, on angiosperm stump, 15 October 2017, Cui 16434 (Holotype, BJFC! isotype in IFP!). Etymology. — Vietnamensis (Lat.): refers to the type specimen collected from Vietnam. Fruitbody. — Basidiomata perennial, pileate, usually solitary, woody hard, without odor or taste when fresh; consistently woody hard and light in weight upon drying. Pileus usually ungulate, projecting up to 5 cm, 7 cm wide and 5.5 cm thick at base. Pileal surface yellowish buff, cinnamon-buff, cinnamon brown to dark brown when fresh, becoming cinnamon to fawn brown upon drying, concentrically sulcate with indistinct wide zones, smooth; margin distinct, yellowish brown to cinnamon brown, obtuse. Pore surface pale yellowish brown to fuscous when fresh, becoming cinnamon-brown to dark brown upon drying; distinctly glancing; pores round, 7 – 9 per mm; dissepiments thin to slightly thick, entire. Context yellowish brown, hard corky to woody hard, up to 5 cm thick. Tubes concolorous with pore surface, woody hard, up to 5 mm long. Hyphal structure. — Hyphal system dimitic; generative hyphae simple-septate; skeletal hyphae IKI –, weakly CB +; tissues darkening but otherwise unchanged in KOH. Context. — Generative hyphae colorless to pale yellowish, fairly thick-walled, branched, 2 – 4 μm in diam; skeletal hyphae dominant, yellowing brown to pale reddish brown, thick-walled with a wide to narrow lumen, occasionally branched, loosely interwoven, 3 – 4.5 μm in diam. Tubes. — Generative hyphae colorless to pale yellowish, fairly thick-walled, branched, 1.4 – 3 μm in diam; skeletal hyphae dominant, yellowish brown to pale reddish-brown, thick-walled with a wide to narrow lumen, occasionally branched, more or less subparallel along the tubes, 2 – 5 μm in diam. Hymenial setae abundant, ventricose, usually hooked, dark brown, thick-walled, 20 – 35 × 8 – 15 μm. Cystidia and cystidioles absent. Basidia barrel-shaped, with four sterigmata and a simple septum at the base, 9 – 15 × 5 – 8 μm, basidioles in shape similar to basidia, smaller than basidia. Irregular crystals frequently present in trama. Spores. — Basidiospores ovoid to broadly ellipsoid, colorless, fairly thick-walled, smooth, weakly dextrinoid, moderately CB +, (5 –) 5.5 – 6 (– 6.5) × (4.5 –) 5 – 5.5 μm, L = 5.87 μm, W = 5.11 μm, Q = 1.15 (n = 30 / 1).	en	Zhu, Lin, Ji, Xing, Si, Jing, Cui, Bao-Kai (2018): Morphological characters and phylogenetic analysis reveal a new species of Phellinus with hooked hymenial setae from Vietnam.
