Phellinus pachyphloeus (Pat.) Pat., Essai Taxon. Hymenom. P. 97. 1900.

 Description: Basidiocarp perennial, ungulate to applanate, dimidiate to sessile, broadly attached, solitary, woody hard, up to 50 cm wide and 12 cm thick at the base; upper surface pale fulvous to dull brown, grayish or blackish from the base, first finely velvety, soon glabrous, sulcate to rugulose in concentric zones, irregularly rimose when dry, with a dark brown to black resinous hard cuticular, up to 2 mm thick. Pores round, 8-10 per mm, concolorous with upper surface, up to 10 cm long. Context concolorous with upper surface. Hyphal system dimitic; generative hyphae hyaline to pale yellow, simple-septate, thin-walled, up to 4 µm wide, skeletal hyphae yellow to pale brown, thick-walled, up to 6 wide. Setal hyphae dark brown, acute, in the dissepiments up to 800 × 30 µm. Hymenial setae pale brown to dark brown, acute, thick-walled, straight or slightly curved on the top, 12-35 × 5-10 µm. Basidiospores hyaline to slightly pale yellow, broadly ellipsoid to globose, thin-walled, smooth, 3.5-5 × 4-5.5 µm. IKI-.

 Note: The acute and wide setal hyphae, and abundant hymenial setae characterize the spe-cies. P. pachyphloeus was usually found on the basal stem of declining trees indicating that it probably had pathogenicity to the hosts.
