 Description: Pileus 2-17 cm wide, plano-convex to plane, sometimes cyathiform, surface dry, opaque, villous then subtomentose, fuligineous umber when young, fuscous rosaceous or vinaceous in age, context 5-11 mm thick in the centre of the pileus, soft, spongy, pale yellow, reddish brown below the surface of the pileus, turning blue on exposure especially above the gills (not reddening or blackening). Stipe 4-6.5 cm × 3-7 mm, cylindric, stout, the base attenuate and attached by yellowish white fibrils, surface brown, rufescent or reddish, paler downwards, wholly finely brown or reddish scurfy pruinose, the apex often yellow and ribbed by the gills, context solid, color brightly yellow, staining reddish at base on exposure. Gills lurid golden yellow with rubellous edges, deeply decurrent, 4-13 mm wide, 3-4 ranks, cyanescent on bruising. Spores 11-16.5 × 5-6 μm, brown in KOH, mostly brown and some ochraceous in Melzer's reagent, ellipsoid, smooth. Basidia 43-55 × 9-12 μm, clavate, the base 4-6 μm wide without clamp; sterigmata 7-8 μm long. Pleurocystidia 90-130 × 16-26 μm, ventricose with obtuse apex, very abundant on gill-edge and surface. Caulocystidia 51-103 × 10-17.5 μm, clavate to subventricose. Tube trama of subparallel type, hyphae 5-10 μm wide and mucilaginous hyphae divergent from a central strand; subhymenium 40-50 μm thick with short cells 8-12 × 4-6 μm. Cuticle of pileus a pile of erect, 2-3 septate hyphae 7-13(22) μm wide, the end-cells 32- 120 μm long, cylindric to subclavate or subventricose, apex obtuse, with dense brownish opalescent content.

 Note: This species is evidently a Phylloporus but not conspecific with P. rhodoxanthus (Schw.)Bres. and P. bellus (Mass.)Corner which were collected by Yeh and Chen (1980) and Chen et al. (1994). The flesh of P. orientalis is reddish or reddish brown below the surface of pileus and in stem, its gills are strongly cyanescent on bruising, its stem surface is reddish furfuraceous, and its spores are slightly longer as compared to the other two species. The flesh of P. bellus is pale yellow or, if reddish in the stem, its gills unchanging or slightly cyanescent on bruising, its stem surface is pallid yellow, and its spores are slightly smaller as compared to the other two species. The fresh of P. rhodoxanthus is pale yellow, the areas under the cuticle of pileus and occasionally at the base of stipe are vinous-red flushed, the gill are unchanging or occasionally reddish on bruising, and the stipe surface yellowish with a red coating.
