description: Sanghuangporus quercicola L. Zhu & B.K. Cui, sp. nov. (Figs. 2, 3)   
Basidiomata perennial, mostly pileate, occasionally effused-reflexed, pores angular to circular (7–9 per mm). Hyphal system monomitic in context, dimitic in trama, generative hyphae simple septate. Basidiospores subglobose to ovoid, pale yellowish, fairly thick-walled, smooth, moderately CB+, IKI–.  
MycoBank no: 820457  
 Type. — CHINA. Henan Province, Neixiang County, Baotianman Nature Reserve, on dead tree of Quercus, 25 August 2006, Li 1149 (Holotype, BJFC 004803!).   
 Etymology.— Quercicola (Lat.): refers to occurrence on Quercus.   
 Fruitbody. —Basidiomata perennial, mostly pileate, occasionally effused-reflexed, without odor or taste, hard corky when fresh, becoming hard corky to woody hard upon drying. Pilei applanate, usually dimidiate or semicircular, projecting up to 3 cm, 5 cm wide and 2.5 cm thick at base. Pileal surface yellowish brown, cinnamon brown to dark brown, concentrically zonate and sulcate, velutinate when juvenile, becoming glabrous and slightly rimose with age; margin obtuse, lemon-yellow when juvenile, becoming yellowish brown with age. Pore surface buff-yellow to cinnamon brown, glancing; sterile margin distinct, bright yellow to yellowish brown, up to 2 mm wide; pores angular to circular, 7–9 per mm; dissepiments thin, entire. Context yellowish brown, woody hard, up to 2 cm thick. Tubes concolorous with pore surface, hard corky, up to 5 mm long, tube layers distinct.   
 Hyphal structure. —Hyphal system monomitic in context, dimitic in trama; generative hyphae simple septate; tissues darkening but otherwise unchanged in KOH.   
 Context. —Generative hyphae yellow to golden brown, thin- to thick-walled, frequently simple septate and branched, more or less straight, loosely interwoven, 2–4 μm in diam; hyphae in the white mycelia strands hyaline, thin- to slightly thick-walled, readily septate, moderately branched, 2–4.2 μm in diam.   
 Tubes. —Generative hyphae colorless to yellowish brown, thin- to thick-walled, frequently simple septate, occasionally branched, 1.4–3 μm in diam; skeletal hyphae dominant, yellowish brown, thick-walled with a wide to narrow lumen, usually unbranched, interwoven, 1.8–4 μm in diam. Hymenial setae abundant, mostly ventricose or subulate, dark brown, thick-walled, 14–35 × 6–9 μm. Cystidia absent, cystidioles present, fusoid, thin-walled, 12–18 × 2.5–5 μm. Basidia barrel-shaped, with four sterigmata and a simple septum at the base, 5–9 × 4–5 μm; basidioles mostly capitate, in size similar to basidia. Irregular crystals frequently present in trama and hymenia.   
 Spores. —Basidiospores subglobose to ovoid, pale yellowish, fairly thick-walled, smooth, moderately CB+, IKI–, (2.5–)3–3.9(–4) × (2.2–)2.4–2.8(–3) μm, L = 3.23 μm, W = 2.66 μm, Q = 1.18–1.24 (n = 90/3).
