Mu & L. P. Tang 2021	<div><p>Amanita fense M. Mu &amp; L.P. Tang, sp. nov. (Figs. 3–4).</p> <p>MycoBank: MB 835965.</p> <p>Etymology:—“ fense ” means pinkish, pale rose in Chinese, and refers to the color of the lamellae.</p> <p>Diagnosis:—Belonging to Amanita section Caesareae, characterized by a buff to cacao brown pileus; a narrow subhymenium (2–3 cells thick); pinkish white to light pink lamellae; membranous annulus; ellipsoid to elongate and inamyloid basidiospores (11.5–14.0 × 8.0–10.0 µm with Q = 1.38–1.63 and Q m = 1.52 ± 0.09); abundant clamps.</p> <p>Holotype:— CHINA. YUNNAN PROVINCE: Yongsheng County, 26°40′23”N, 100°43′19”E, elev. 2655 m, 2nd October 2018, H. Y. Huang 174 (MHKMU-Huang174).</p> <p>Gene sequences ex-holotype:— MT108790 (ITS); MT138689 (LSU).</p> <p>Description:— Basidiomata medium-sized, mostly solitary. Pileus 5–8 cm in diam, plano-convex to applanate, shiny,</p> <p>slightly viscid when moist, surface buff to cacao brown (5C3–5, 5D4–6, 6C6) when young, then golden brown (5D5–</p> <p>7, 6D6) to bronze brown (5E5– 8, 6E 5–6), dark at the center, covered with pearl white (3B1) or grayish white (29B1,</p> <p>30B1) cottony-floccose scales, paler towards the margin when old; margin striate 0.3–0.4 R (or 30–40% of the radius);</p> <p>trama pale white, thin. Lamellae 0.5–0.9 cm broad, free, pinkish white, pale pink or shell pink (8A2–3, 9A2, 10A2), the pink tones becoming more obvious after drying, unchanging when injured, moderately crowded, 70–80 complete lamellae/cap, 1–2 lamellulae between two complete lamellae, lamellulae subtruncate to truncate. Stipe 7–10 cm long × 0.7–1.1 cm diam, surface white (1A1) with faint pink hues, cylindrical, attenuated upwards, hollow in center, context pinkish white or pale pink (9A2, 10A2). Basal bulb absent. Volval remnants on the stipe base saccate 2.0–2.8 × 1.4–1.8 cm diam, soft, white, off-white (1A1) to pinkish white (9A2, 10A2). Annulus persistent, upper-middle, thin, small, membranous, fragile and easily detached, estriate, white. Odor indistinct.</p> <p>Basidiospores [80/4/4] (11.0–) 11.5–14.0 (–14.5) × (7.5–) 8.0–10.0 (–10.5) µm, Q = (1.33–) 1.38–1.63 (–1.67), Q m = 1.52 ± 0.09, ellipsoid to elongate, inamyloid, thin-walled, hyaline, smooth; apiculus small about 1 µm long. Basidia 40–49 × 12–14 µm, clavate, 4-spored; sterigmata 4–6 µm long, basal septa clamped. Lamellar trama bilateral. Mediostratum 30–40 µm thick, composed of filamentous hyphae and ellipsoid to subfusiform inflated cells. Lateral stratum consisting of abundant ellipsoid to elongate ellipsoid inflated cells and scattered thin-walled regular hyphae, 3–7 µm wide. Subhymenium 28–40 µm thick, with 2–3 layers of pyriform inflated cells, 10–22 × 7–18 µm. Lamellar edge somewhat gelatinized, composed of hyaline, numerous subglobose, clavate or pyriform inflated cells 20–40 × 10– 20 µm and 3–5 µm wide filamentous hyphae, single or in short chains, running parallel to the lamellar edge. Pileipellis 30–80 µm thick; upper layer 20–40 µm thick, slightly gelatinized, filamentous hyphae 1–4 µm wide, hyaline, radially arranged; lower layer 15–40 µm thick of filamentous hyphae 2–8 µm wide, colorless, radial or interwoven, compact. Pileus context made up of abundant thin-walled inflated cells, 45–90× 20−40 µm; mixed with filamentous hyphae 3–5 µm diam, thick-walled (about 1–1.5 µm thick), clamped. Volval remnants on the stipe base dominantly composed of abundant longitudinally arranged 3–7 µm wide, colorless, thin-walled filamentous hyphae; scattered to fairly abundant inflated cells, subglobose to ellipsoid, 40–90 × 25–55 µm, colorless, thin-walled. But inflated cells of the outer layer of the volval remnants more abundant than the inner layers. Stipe trama mainly composed of longitudinally arranged, long, clavate, 90–200 × 25–45 µm terminal cells and 2–10 µm wide filamentous hyphae. Annulus consisting mainly of radially arranged hyphae, 2.5–7 µm wide, colorless, thin or slightly thick-walled; inflated cells scarce, ellipsoid to elongate, clavate to broad clavate, 20–40 × 9–15 µm, colorless, thin-walled, often single and terminal. Clamps present in all tissues of basidiomata.</p> <p>Known distribution and habitat:— CHINA. Anhui, Liaoning, Yunnan province.
