Decock & Yombiy. (2015: 1007) ( Figs. 4 and 5 ) Description: –Basidiocarps annual, pileate, sessile, imbricate, hard corky when dry. Pilei semicircular, dimidiate or flabelliform, conchate to applanate, projecting up to 5 cm long, 7 cm wide, and 0.6 cm thick at base. Pileal surface yellowish brown to greyish brown with dust, finely tomentose with age, concentrically sulcate to the margin, faintly zonate to the base; margin sharp. Pore surface pinkish buff to cinnamon when fresh; sterile margin distinct, yellowish, up to 2 mm wide. Pores usually round, 8–10 per mm; dissepiments thin, entire. Context up to 3 mm thick, duplex, separated by a black line, the lower context corky, greyish brown, up to 1 mm thick, the upper context soft, spongy, cinnamon, with a tomentum, cinnamon, up to 1.5 mm thick. Tubes honey yellow, corky, up to 3 mm long. FIGURE 4. Basidiocarps of Phylloporia pulla (LWZ 20190428-3). Photos by: Xue-Mei Tian. Hyphal system dimitic; generative hyphae simple septate; tissue darkening but otherwise unchanged in 5% KOH. Context generative hyphae hyaline to pale yellowish, thin- to fairly thick-walled, occasionally branched, 2–3.5 µm in diam; in the lower context, skeletal hyphae golden yellow, thick-walled with a narrow lumen, unbranched, fractured and short, 2–4 µm in diam; in the upper tomentum, skeletal hyphae golden yellow, thick-walled with a narrow to wide lumen, unbranched, aseptate, loosely interwoven, 3.5–5 µm in diam; in the black zone, hyphae dark brown, thick-walled with a narrow lumen, interwoven. Tubes generative hyphae hyaline, thin to slightly thick-walled, occasionally branched, 2–3 µm in diam; skeletal hyphae dominant, golden yellow, thick-walled with a narrow lumen, unbranched, occasionally septate, interwoven, 2.5–4 µm in diam. Cystidia and cystidioles absent. Basidia broadly clavate, with four sterigmata and a simple septum at the base, 8–10 × 4–5 µm; basidioles similar to basidia in shape, but slightly smaller. Basidiospores broadly ellipsoid, yellowish, thin to fairly thick-walled, smooth, inamyloid and non-dextrinoid in Melzer’s reagent, acyanophilous, (2.5–)2.7–3.3 × (2.0–) 2.1–2.5 µm, L = 2.91 µm, W = 2.32 µm, Q = 1.21–1.30 (n = 60/2). Specimens examined. CHINA . Shandong Province : Zibo, The Great Wall of Qi, on living Pyrus , 28 April 2019 , LWZ 20190428-2 (HMAS), LWZ 20190428-3 (HMAS), LWZ 20190428-4 (HMAS). Notes:—The Chinese specimens of Phylloporia pulla have almost identical morphological characters to the holotype of this species from Indonesia but differ by much larger basidiocarps and darker color of pileal surface covered by dust ( Yombiyeni et al. 2015 ). Moreover, their nLSU sequences are almost identical to the isotype of Polyporus schmidtii Rostr. (1902: 360) from Thailand , a synonym of Phylloporia pulla ( Ryvarden 1976 ; Wu et al. 2019 ).
