Perenniporia subcorticola Chao G. Wang & F. Wu, sp. nov. 2020
MycoBank No: 835519
Holotype: China. Fujian Province, Wuyishan Nature Reserve, on rotten wood of Pinus, 21.X.2005, Y.C. Dai 7330 (BJFC001421).
Morphological description
Basidiocarps. Perennial, resupinate, soft corky and without odour or taste when fresh, becoming corky when dry, up to 10 cm long, 5 cm wide, 3.5 mm thick at centre. Pore surface yellow when fresh, becoming buff-yellow to curry-yellow when dry; margin narrow, thinning out; pores tiny, round, 7–8 per mm; dissepiments thick, entire. Subiculum thin, cream, up to 2 mm thick. Tubes concolorous with pore surface, up to 1.5 mm long.
Hyphal structure. Hyphal system dimitic; generative hyphae with clamp connections; skeletal hyphae weakly dextrinoid, CB+; tissues darkening in KOH.
Subiculum. Generative hyphae infrequent, hyaline, thin-walled, occasionally branched, 2–3 μm in diam.; skeletal hyphae dominant, thick-walled with a wide lumen, frequently branched, interwoven, 2–3.5 μm in diam.
Tubes. Generative hyphae infrequent, hyaline, thin-walled, occasionally branched, 2–3μm in diam.; skeletal hyphae dominant, thick-walled with a wide lumen, frequently branched, interwoven, 1.8–3 μm in diam. Cystidia absent, fusoid cystidioles present, hyaline, thin-walled, 14–18 × 4.5–7.5 μm; basidia barrel-shaped, with four sterigmata and a basal clamp connection, 13–16 × 6.5–9 μm; basidioles dominant, mostly pearshaped to capitate, slightly smaller than basidia.
Spores. Basidiospores ellipsoid, truncate, hyaline, thick-walled, smooth, dextrinoid, CB+, (4–)4.2–5(–5.5) × (3–)3.5–4.2(–4.7) μm, L = 4.66 μm, W = 3.91 μm, Q = 1.16–1.23 (n = 60/2).
