Guizhou Province, Guiyang, Qianlingshan Forest Park, E 106 ° 41 ' 19 " – 106 ° 41 ' 55 ", N 26 ° 35 ' 24 " – 26 ° 36 ' 37 ", elev. 1100 – 1396 m., on a fallen trunk of Pinus massoniana, 21 August 2023, Dai 25825 (Holotype, BJFC 043374). Holotype DNA sequences: PP 356579 (ITS), PP 356577 (LSU). Description: — Basidiomata annual, resupinate, soft, and lemon chrome when fresh, cinnamon buff, fragile when dry, up to 16 cm long, 7 cm wide, and approximately 1.2 cm thick at the center; sterile margin narrow, up to 0.5 mm wide. Pores angular to irregular, mostly 3 – 4 per mm, but sometimes 1 – 2 per mm; dissepiments very thin, lacerate; subiculum very thin to almost absent, less than 0.1 mm thick; tubes concolorous with pore surface to buff, up to 1.1 cm long. Hyphal system monomitic; generative hyphae bearing clamp connections, IKI –, CB –, tissues becoming purple in KOH. Subicular generative hyphae thick-walled, rarely branched, 3 – 5 µm in diam., frequently encrusted with fine yellow crystals. Tramal hyphae hyaline, thick-walled, rarely branched, frequently bearing clamp connections, 3 – 4 µm in diam.; hyphae at dissepiment edge swollen, up to 4 – 5 µm in diam. Cystidia and cystidioles absent; basidia more or less barrel-shaped, hyaline, bearing four sterigmata and a basal clamp connection, 12 – 15 × 4 – 5 μm; basidioles in shape similar to basidia, but slightly shorter. Basidiospores ellipsoid with tapering apiculus, hyaline, thin-walled, smooth, usually with one or two guttules, IKI-, CB-, (2.8 –) 2.9 – 3.8 (– 4.2) × (1.8 –) 1.9 – 2.4 (– 2.7) µm, L = 3.30 µm, W = 2.19 µm, Q = 1.43 – 1.60 (n = 60 / 2). Additional specimens (paratypes) examined: — CHINA. Yunnan Province, Puer, Puer Forest Park, E 101 ° 16 ′ – 103 ° 09 ′, and N 23 ° 19 ′ – 24 ° 53 ′, elev. 1300 – 1350 m., on rotten angiosperm wood, 17 August 2019, Dai 20429 (BJFC 032097). Habitat and ecology: Luteoporia tenuissima is currently known in subtropical central and southwestern China, where it grows on dead Pinus massoniana and angiosperm wood.	en	Luo, Kai-Yue, Yuan, Yuan, Liu, Hong-Gao, Ghobad-Nejhad, Masoomeh, Dai, Yu-Cheng (2024): Luteoporia tenuissima sp. nov.
