description: 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).
