03C3740FFFDE3373FF6FFD586FAF72D8.taxon	diagnosis	Diagnosis: — Morphologically similar to Pluteus aurantiorugosus but differing mainly by the cheilocystidia with a short to long apical rostrum, clustered caulocystidia, larger basidiospores (6.0 ‒ 8.0 × 5.5 ‒ 7.0 μm), and distinct nrITS sequence.	en	Xu, Jiang, Hosen, Md.

03C3740FFFDE3373FF6FFD586FAF72D8.taxon	description	Description: — Basidiomata small. Pileus 8 ‒ 20 mm in diam., obtusely conical to hemispherical when young, expanding to convex, plano-convex or applanate, often with a low umbo, non hygrophanous, striate at margin, bright orange-red (7 A 7 ‒ 7 A 8) to vivid reddish orange (8 A 7 ‒ 8 A 8) when young, orange (6 A 7 ‒ 6 A 8) to orange-yellow (4 A 8 ‒ 5 A 8) when mature, glabrous; margin indistinctly striate, or lobed and becoming finely rimose, sometimes eroded. Lamellae free, moderately crowded, with lamellulae, ventricose, up to 3 mm broad, whitish to yellowish (5 A 4), sometimes eroded near the pileus margin. Stipe 10 ‒ 34 × 1 ‒ 2.5 mm, cylindrical, equal or slightly enlarged towards base, slightly hollow to solid when mature, yellowish (4 A 7 ‒ 4 A 8) to concolorous with the pileus when mature, pale orange (7 A 4 ‒ 7 A 5) at the base, somewhat translucent, distinctly squamulose over whole length. Context whitish in pileus and yellowish in stipe. Smell indistinct. Taste not recorded. Spore print pale pinkish. Basidiospores [60 / 3 / 2] (5.5 ‒) 6.0 ‒ 8.0 (‒ 8.5) × (5.0 ‒) 5.5 ‒ 7.0 μm (L av = 7.0, W av = 6.1, Q = 1.07 ‒ 1.23; Q m = 1.14), subglobose to broadly ellipsoid, slightly thick-walled. Basidia 18 ‒ 25 × 8 ‒ 11 μm, clavate, 4 - spored, hyaline or with refringent content, thin-walled. Pleurocystidia 25 ‒ 50 × 10 ‒ 22 μm, rare, scattered, clavate to broadly clavate, non-rostrate, hyaline, thin-walled. Lamellar margin sterile. Cheilocystidia 30 ‒ 65 × 10 ‒ 25 μm, abundant, clavate to broadly clavate, with a short to long rostrate apex (up to 20 μm), hyaline, thin-walled. Pileipellis an epithelium, made up of subfusiform to clavate elements, 25 – 62 × 12 – 30 μm, filled with intracellular pigment yellowish brown in 5 % KOH, thin-walled. Stipitipellis a cutis of cylindrical thin-walled hyphae 4 ‒ 15 μm diam, colorless or with brownish intracellular pigment in 5 % KOH. Caulocystidia 26 ‒ 50 × 10 ‒ 21 μm, clavate to fusiform, non-rostrate, thin-walled, present over the entire length of the stipe, usually in clusters, colorless or with brownish intracellular pigment in 5 % KOH. Clamp connections absent in all parts examined.	en	Xu, Jiang, Hosen, Md.
