Ceriporia wuyiana Y. C. Dai, Chao G. Wang & Yuan Yuan 2025, sp. nov.

Ceriporia wuyiana Y. C. Dai, Chao G. Wang & Yuan Yuan sp. nov. Figs 8, 9 Etymology. Wuyiana (Lat.): refers to the species being found in Wuyi County, Zhengjiang Prov., East China. Diagnosis. Differs from other Ceriporia species by resupinate basidiomata with a white to cream pore surface when fresh, clay pink to pale lavender when dry, round to angular pores of 5–6 per mm, subicular hyphae relatively wider than tramal hyphae, allantoid to lunate basidiospores measuring 4.3–5 × 1.7–2 µm. Type. CHINA • Zhejiang Province, Wuyi County, Guodong Forest Park, on rotten angiosperm wood, 19 June 2023, Dai 24998 (BJFC 042551, holotype). Description. Basidiomata annual, resupinate, soft, without odor or taste when fresh, soft when dry, up to 6 cm long, 2.5 cm wide, and 0.2 mm thick at the center. Pore surface white to cream when fresh, becoming clay pink to pale lavender upon drying; sterile margin indistinct to almost lacking; pores round to angular, 5–6 per mm; dissepiments thin, lacerate. Subiculum very thin to almost absent. Tubes concolorous with pore surface, soft when dry, up to 0.2 mm long. Hyphal system monomitic; generative hyphae simple septate, hyaline, IKI -, CB +; tissues becoming orange-brown in KOH. Subicular hyphae thin- to slightly thick-walled with a wide lumen, abundantly covered with small, rhombic, hyaline crystals and oily substances, sometimes encrusted with fine crystals, frequently branched at more or less a right angle, straight, slightly interwoven, 4–5 µm in diam. Tramal hyphae thin-walled with a wide lumen, abundantly covered with rhombic or irregular pale orange crystals and oily substances, sometimes encrusted with fine crystals, frequently branched, straight to slightly flexuous, subparallel along the tubes, agglutinated, 3–4 µm in diam. Cystidia and cystidioles absent. Basidia barrel-shaped to somewhat pyriform, with four sterigmata and a simple basal septum, 9–12.5 × 4–5 µm; basidioles of similar shape to basidia, but smaller. Basidiospores allantoid to lunate, hyaline, thin-walled, smooth, IKI -, CB -, (4.1 –) 4.3–5 × (1.5 –) 1.7–2 µm, L = 4.58 µm, W = 1.83 µm, Q = 2.51 (n = 30 / 1). Notes. Ceriporia wuyiana is similar and related to C. punicans Vlasák & Spirin by subicular hyphae relatively wider than tramal hyphae and almost the same size as basidiospores (4.1–5.3 × 1.7–2.1 µm vs. 4.3–5 × 1.7–2 µm, Spirin et al. 2016). However, the latter has a white or pale pink pore surface when fresh, orange to pinkish orange when dry, and entire dissepiments (Spirin et al. 2016).
