MycoBank no.—MB 852491
Etymology:— Tenuissima (Lat.): Refers to the species having a very thin subiculum.
Type:— CHINA. Guizhou Province, Guiyang, Qianlingshan Forest Park , E106°41'19" –106°41'55", N26°35'24" – 26°36'37", elev. 1100–1396 m., on a fallen trunk of Pinus massoniana , 21 August 2023, Dai 25825 (Holotype, BJFC043374 About BJFC ). Holotype DNA sequences: PP356579 ( ITS), PP356577 ( LSU). GoogleMaps
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, E101°16′ – 103°09′, and N23°19′ –24°53′, elev. 1300–1350 m., on rotten angiosperm wood, 17 August 2019, Dai 20429 (BJFC032097).
Habitat and ecology: Luteoporia tenuissima is currently known in subtropical central and southwestern China, where it grows on dead Pinus massoniana and angiosperm wood.
