| Description： |
Basidiocarp pileate, perennial, broadly attached, imbricate in clusters, often large, up to 12 cm wide, 25 cm long and up to 10 cm thick at the base, often triquetrous in section, woody when dry. Pileus surface glabrous, slightly zonate, often with small warts or thin ridges, first ochraceous, becoming unevenly dirty brown to grey, margin rounded. Pore surface cork or woodcolored, pores 4-6 per mm. Tubes stratified, pinkish-ochraceous to corkcolored. Context cottony to punky, isabelline to pale cork colored, up to 4 cm thick at the base. Hyphal system dimitic, generative hyphae hyaline, thin-walled, rather variable in width, mostly 2-6 μm wide, with small clamps, skeletal hyphae dextrinoid, straight to flexuous, 3-7 μm wide. Basidiospores subglobose to dropshaped, thick-walled, variably dextrinoid, 6-8 × 5-6.5 μm. | |||
