(GenBank: ITS: MH697850 and LSU: MH712739 ).</p><p>Etymology:—The epithet  subalbocrenulata refers to the similarity to  Hemistropharia albocrenulata .</p><p>Description:— Pileus 2.2–3.9 cm in diameter, dark reddish orange to dark brown (10.0R 5/8-5/10), viscid, convex to hemispherical when young, becoming broadly convex to nearly plane, sometimes with an obtuse umbo, not hygrophanous, no striate, with whitish to pale brownish yellow (7.5Y 9/2), fibrillose squamules formed by remnants of the veil; margin slightly involute to deflexed, frequently decorated with veil fragments. Context slightly thick, whitish to pale yellow (5.0Y 9/2); odor and taste not distinctive. Lamellae whitish to pale purplish gray (2.5PB 9/2), adnate to sinuate, close, broad; edges white and crenulate. Stipe 4.2–5.5 cm long, 0.5–0.9 cm thick, whitish to yellowish (7.5Y 9/2), central, equal to slightly enlarged at base, stuffed; surface dry, decorated with yellowish brown (2.5YR 6/8), subfloccose to recurved scales below the floccose-cottony evanescent annulus, pruinose to silky at the apex. Spore print dark rusty brown (5.0YR 3/8).</p><p>Basidiospores 10.5–14(–24) × 5.5–7(–10) μm, [Q = 1.75–2.82], some spores are unusually large (18–24 ×8–10μm), wide-fusoid, fusoid to subfusoid, wall appreciably thickened, smooth, with a distinct germ pore, content homogeneous to inhomogeneous with some amorphous, refractive, oily inclusion, brown in KOH at maturity, unchanged in Melzer’s reagent. Basidia 24.0–35.0 × 5.0–7.0 μm, 2-, or 4-spored, clavate, hyaline in KOH. Cheilocystidia abundant, 25– 55 × 5–9 μm, narrowly clavate, cylindric-capitate to flexuous with an apical capitellum, rarely subglobose with a short pedicel, thin-walled, smooth, hyaline, with homogeneous contents. Pleurocystida 40–50 × 7–10 μm, clavate-rostrate, the long neck, sometimes flexuous, apex acute to obtuse, content hyaline to yellow, homogeneous, sometimes with crystalline substance. Caulocystidia not observed. Lamellar trama regular; hyphae hyaline in KOH, smooth. Pileipellis a gelatinous layer of hyaline to light yellow hyphae, ixocutis, 4–9 μm in diam., thin-walled, smooth to slightly roughened. Clamp-connections present in all tissues.</p><p>Habitat:—Scattered on rotten hardwood in conifer-broadleaf mixed forest, from summer to autumn.</p><p>Additional materials examined:—   CHINA.

However, we can easily distinguish the former from the latter based on both micromorphological features and other macro-characteristics. The former has conspicuous,clavate-rostrate pleurocystidia with flexuous neck, larger basidiospores, and smaller basidiomata, as well as a whitish stipe; but the latter has no pleurocystidia, comparatively smaller basidiospores (11–14 × 5.5–7 μm), larger basidiomata (pileus, 3–10 cm broad) and darker stipe (Jacobsson &amp; Larsson, 2007). Furthermore, in our phylogenetic analysis,  H. subalbocrenulata clustered with  H. albocrenulata forming the  Hemistropharia clade with the high statistical support (BPP = 1), but it represented a relatively independent lineage within it (Figure 1). Therefore, it is proposed here as a new species of the genus  Hemistropharia .</p></div>	https://treatment.plazi.org/id/C24D87E8FFDAEE4B0584EB5E6C96FDF2	Public Domain	No known copyright restrictions apply.
