Ma & K. D. Hyde 2014	<div><p>Psilocybe chuxiongensis T. Ma &amp; K.D. Hyde, sp. nov. (Fig. 4)</p><p>MycoBank MB805509</p><p>Differs from related Psilocybe species mainly by the absence of annulus and hemispheric to hemispheric-convex pileus without an umbo or papilla.</p><p>Type:— CHINA. Yunnan Province: Chuxiong City, Zixi Mountain, on cow dung, 25°01′05.5"N, 101°23′19.9"E, elevation 2237 m, 20 August 2009, Tao Ma CX026 (IFRD414-010, holotype!) .</p><p>Pileus 26–38 mm diameter, at first conic or hemispheric-conic with incurved margin, then hemispheric to hemispheric-convex, not umbonate or papillate, dark yellow (4B4; Buff-Yellow) to yellowish brown (4B8; Aniline Yellow), sometimes darker in centre, often becoming paler towards the edge and almost whitish at margin, becoming beige when dry; surface smooth, slightly viscid when moist; margin even, entire, decorated with somewhat fugacious, white to bluing, membranous veil remnants; context yellowish (2A3,Celonial Buff). Lamellae adnate-sinuate, 4–6 mm high, close or subdistant, yellowish waxy-white when young, becoming pale grayish yellow with purple-brown (8E5) mottles when matured, then olive ochre (2C5) to dark brown, edges serrulate and remaining whitish, turning bluish during drying or when handled. Stipe 50–68 mm × 3.5–4.5 mm, equal, slightly flexuous, longitudinally striate, hollow and fragile, white with sheen, becoming beige when dry; surface somewhat bluish when touched or bruised, or on drying, covered with white floccose scales which become bluish when touched; base of stipe with white mycelium; annulus absent; context concolorous with that of pileus, whitish towards the surface. Odor mild. Some mycelium in centre of colony bluish in culture.</p><p>Pileipellis an ixocutis, 20–200 µm thick, made up of creeping, hyaline and colourless, subregular to interwoven, 1–4 µm wide filamentous hyphae, occasionally with dark or blackish finely incrusting pigments; subpileipellis dark yellow in KOH, composed of subregular, colourless to yellowish, filamentous to inflated, 2–16 µm wide hyphae. Subhymenium subcellular, composed of irregular vesiculose to subglobose cells, 3–13.5 × 2–12 µm, hyaline, colourless to yellowish, thin-walled to slightly thick-walled (about 0.5 µm). Hymenophoral trama regular, with cylindrical hyphae 2–13 µm diam, hyaline, colourless to yellowish, thin-walled to slightly thickwalled (≤1.0 µm). Basidia (24–) 30–44 (–53) × 8–14 µm, hyaline and colourless, occasionally yellowish, clavate to broadly clavate, narrowed in lower half or with a short to very long base 8–26 (–30) µm × 2–6 µm wide, 4- spored, sometimes 2-spored; sterigmata 3–6 (–8) µm. Basidiospores (241/5/2) (12–) 13–16 (–19) × (7–) 8–10.5 × 7.5–10 (–11) µm, often ellipsoid, elongate-ellipsoid to subhexagonal, occasionally ovoid, broadly ellipsoid, subrhomboid or subfusiform in face view, Q = (1.4–) 1.5–1.8 (–2.4), Q = 1.63±0.13; ellipsoid, subellipsoid to nearly oblong in side view, Q = (1.4–) 1.5–1.8 (–2.0), Q = 1.65±0.10, yellowish brown with purple tinge in water, yellowish brown in KOH, dark purplish brown in deposit; wall smooth, slightly thick to thick (0.5–1.5 µm), complex, with distinct 1–2 µm wide apical germ pore. Cheilocystidia 22–42 (–46) × 5–10.5 µm, hyaline, narrowly clavate, clavate or lageniform-clavate, sometimes lageniform or fusoid-ventricose, occasionally similar to pleurocystidia, but narrower, with a (2–) 3–11 × 1.5–4 µm subcapitate tip or neck, rarely forked. Pleurocystidia relatively rare and scattered, 24–42 (–48) × (8–) 9–15 µm, thin-walled, hyaline, ventricose to broadly clavate and fusoid-clavate, often narrower near the apex, obtuse to short rostrum (2–4 × 2–4 µm). Caulocystidia 23–54 × 6–10 (–14) µm, clustered at the upper part of the stipe, thin-walled, hyaline, some of them similar to cheilocystidia, narrowly clavate to lageniform, some oblong-subclavate, with short rounded rostrum, subcapitate apex or neck, 2.5–8.5 (–9.5) × 2–4.5 (–6) µm, sometimes irregularly branched. Clamp connections common in all parts of the basidioma.</p><p>Etymology:—Refers to the location Chuxiong, where the collections were found.</p><p>Distribution:—Chuxiong, Yunnan Province, China</p><p>Habitat:—Growing solitary to scattered and gregarious on cow dung or grassland where cattle have grazed in summer and early autumn.</p><p>Other material:— CHINA, Yunnan Province: Chuxiong, Wuding County, near a reservoir at road side in Bailu Village, on soil of grassland where cattle have grazed, 25°39′25.6"N, 102°05′30.0"E, elevation 2523 m, 24 Sep 2012, Xiao-Fei Lin WD007 (IFRD414-011!)</p></div>	https://treatment.plazi.org/id/038D87FDFFE2774518FBF891FD42FB83	Public Domain	No known copyright restrictions apply.
