Phlebiporia bubalina
Phlebiporia bubalina Jia J. Chen, B.K. Cui & Y.C. Dai 2014, , in Chen & Cui, Mycological Progress, 13, 563-573 (2014).
Etymology. bubalina (Lat.): referring to the cream to buff pore surface.
Diagnosis: Basidiomata annual, resupinate, strongly attached to the substrate, corky, without odor or taste when fresh, hard corky upon drying, up to 11 cm long, 4.5 cm wide, 1 mm thick at the center. Sterile margin narrow, cream to buff, up to 1 mm wide. Pore surface cream to cream buff when fresh, buff to pinkish buff when dry; pores round to angular, 6–9 per mm; dissepiments thin, entire to lacerate. Subiculum cream to pinkish buff, corky, very thin to almost lacking. Tubes concolorous with pore surface, hard corky, up to 1 mm long. Hyphal structure. Hyphal system monomitic; generative hyphae simple-septate, dextrinoid, CB+; tissues changed to brownish in KOH. Subiculum. Generative hyphae hyaline to yellowish brown, thick-walled with a wide lumen, frequently simple septate, occasionally branched, flexuous, interwoven, 2–4.5 μm in diam. Quasi-binding hyphae present, thin-walled, frequently branched. Tubes. Generative hyphae hyaline to pale yellowish brown, thick-walled with a distinct lumen, frequently simple septate and branched, flexuous, subparallel along the tubes, 2–4 μm in diam. Cystidia absent, fusoid cystidioles present, hyaline, thin-walled, 9–16×2–3 μm; basidia subclavate to barrel-shaped, bearing four sterigmata and a basal simple septum, 14–17×4–7 μm; basidioles in shape similar to basidia, but slightly smaller. Spores. Basidiospores ellipsoid, hyaline, thin-walled, mostly bearing one to two small guttules, smooth, IKI–, CB–, 3–4(–4.2) × (1.9–)2–2.4(–2.5) μm, L=3.53 μm, W=2.15 μm, Q=1.61–1.67 (n =60/2). Type of rot. White rot.
Index Fungorum Number: IF804627
Figure 1. Strict consensus tree illustrating the phylogeny of Phlebiporia bubalina and related species generated by maximum parsimony based on combined ITS + nLSU sequences. Parsimony bootstrap values (before the slash markers) higher than 50 % and Bayesian posterior probabilities (after the slash markers) more than 0.95 are indicated along branches.
