Phylloporia lonicerae W.M. Qin, Xue W. Wang, T. Sawahata & L.W. Zhou (2018: 21) ( Figs. 2 and 3 )

Description: –Basidiocarps annual, pileate, sessile, imbricated, hard corky when dry. Pilei semicircular, laterally fused, applanate, projecting up to 1 cm long, 2 cm wide, and 0.4 cm thick at base. Pileal surface dull brown in old parts, yellowish brown in young parts, velutinate, glabrescent with age, concentrically sulcate; margin sharp. Pore surface honey yellow when fresh; sterile margin distinct, pale yellow to honey yellow, up to 2.5 mm wide. Pores circular to angular, 6–8 per mm; dissepiments thin, entire. Context up to 2 mm thick, duplex, separated by a black line, the lower context corky, olivaceous buff, up to 1 mm thick, the upper context soft, spongy, cinnamon-buff, with a tomentum, yellowish brown, up to 1 mm thick. Tubes honey yellow, corky, up to 2 mm long.

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, 2–4 µm in diam; in the lower context, skeletal hyphae golden yellow, thick-walled with a narrow lumen, unbranched, 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 µm in diam; in the black zone, hyphae dark brown, thick-walled with a narrow lumen, interwoven. Tubes generative hyphae hyaline, slightly thick-walled, occasionally branched, 2–3.5 µm in diam; skeletal hyphae dominant, golden yellow, thick-walled with a narrow lumen, unbranched, occasionally septate, interwoven, 2.5–4 µm diam. Cystidia and cystidioles absent. Basidia broadly clavate, with four sterigmata and a simple septum at the base, 9–12 × 4.5–6 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–)2.8–3.5(–3.6) × (2.0–)2.2–2.8(–3.0) µm, L = 3.13 µm, W = 2.47 µm, Q = 1.25–1.29 (n = 60/2).

Specimens examined. CHINA. Shandong Province: Linyi , Pingyi County, on living Lonicera japonica , 9 August 2019, LWZ 20190809-1 ( HMAS) ; Fei County, on living Lonicera japonica , 9 August 2019, LWZ 20190809-2 ( HMAS), 19 August 2019, LWZ 20190819-1 ( HMAS) .

Notes. Phylloporia lonicerae was only described from Japan on Lonicera japonica ( Qin et al. 2018) . The Chinese specimens were found on the same host, but they have slightly smaller basidiospores compared with the measurements given in original description (3.2–4 × 2.3–3.1 µm, Qin et al. 2018).
