080C2464B87FFFAFFF5DFA5D8E807B02.taxon	etymology	Etymology: Latin “ wusangongii ” is in honor of Wu Sangong, the originator of shiitake mushroom, who was the founder of the world's " cutting flowers " cultivation technique. Diagnosis: Differs from other species of Aureoboletus by a stipe with distinctly coarse-lacerate reticulations, large basidiospores with longitudinal ridges, and subcutis pileipellis. Holotype: CHINA. Zhejiang Province: Lishui City, Qingyuan County, Baishanzu National Forest Park, elev. 1200 m, 14 August 2023, N. K. Zeng 7864 (FHMU 7702). GenBank accession number: 28 S = PQ 278704, tef 1 = PQ 274248, rpb 2 = PQ 274250, ITS = PQ 278706. Basidiomata small, medium to large-sized. Pileus 4.3 – 11.8 cm diam, hemispherical, then convex; surface viscid when wet, densely covered with grayish-white (1 B 1) to white (1 A 1) fluffs, caducous, turning pale ochre (7 A 5 – 7 B 5) to light brown (6 B 5 – 6); margin straight to slightly incurved, entire; context 0.2 – 0.7 cm thick in the center of the pileus, white (1 A 1) to pinkish (6 A 2), unchanging in color when injured. Hymenophore poroid, depressed around apex of stipe; pores angular to subround, light yellow (1 A 3) to grayish yellow (30 A 3 – 4), or pale yellowish green (30 A 5), unchanging in color when injured; tubes 0.3 – 1 cm in length, light yellow (1 A 3 – 4), unchanging in color when injured. Stipe 9.3 – 13 × 1.2 – 1.7 cm, central, solid, subcylindrical; surface ochre (7 B 5 – 7 B 6) to light reddish-brown (7 A 3 – 4), with distinctly coarse-lacerate reticulations; context yellowish white (2 A 3), unchanging in color when injured. Basal mycelium white (1 A 1). Odor indistinct. Basidiospores [100 / 5 / 4] 15 – 16.24 – 17.5 (– 18) × 7 – 8.33 – 9 (– 10) μm, Q = 1.78 – 2.13 (– 2.29), Qm = 1.96 ± 0.12, yellow in KOH, elongate to cylindrical, slightly thick-walled (0.8 – 1.5 μm), with longitudinal ridges, 3 – 5 ridges visible in lateral view, projecting 0.5 – 2.5 μm wide; ridges continuous or forked, cleft at the apex, lacking cross-striations on the ridges observed under the light microscope. Basidia 37 – 50 × 13 – 17 μm, subclavatet, slightly thick-walled (0.5 – 1 μm), 4 - spored, colorless to yellowish in KOH; sterigmata 2 – 7 μm in length. Hymenophoral trama composed of thin to slightly thick-walled (up to 0.5 μm) hyphae, 4 – 15 μm wide, colorless to yellowish in KOH. Pleurocystidia 60 – 83 × 10 – 17 μm, abundant, subfusiform, slightly thick-walled (up to 1 μm), colorless to yellowish in KOH, no encrustations. Cheilocystidia 58 – 73 × 14 – 20 μm, abundant, subfusiform, slightly thick-walled (up to 1 μm), colorless in KOH, no encrustations. Pileipellis a subcutis 140 – 270 μm thick, composed of slightly thick-walled (up to 1 μm) hyphae, 5 – 11 μm wide, colorless to yellowish in KOH; terminal cells 35 – 93 × 6 – 11 μm, clavate to cylindrical. Pileal trama composed of slightly thick-walled (up to 1 μm) hyphae, 4 – 19 μm wide, colorless in KOH. Stipitipellis a trichodermlike structure 93 – 170 μm thick, composed of slightly thick-walled (up to 1 μm) hyphae, 4 – 11.5 μm wide, colorless to yellowish in KOH; terminal cells 40 – 52 × 6 – 10 μm, subclavate to subfusiform. Stipe trama composed of parallel hyphae, slightly thick-walled (0.5 – 1 μm), 5 – 18 μm wide, subcylindrical, colorless in KOH. Clamp connections absent in all tissues. Habitat: Solitary or gregarious on the ground in forests dominated by fagaceous trees. Known distribution: Eastern China (Zhejiang Province). Additional specimens examined: CHINA.
