 Description: Basidiocarp effuse, separable, membranaceous or subceraceous, 150-500 μm thick in section. Hymenial surface Pale Ochraceous-Salmon, Pinkish Buff, or Warm Buff, usually becoming permanently purple in KOH, smooth or slightly tuberculate, cracked in old parts; margin paler, usually thinning, pruinose, sometimes rather determinate. Hyphal system monomitic; hyphae simple-septate. Subiculum uniform, composed of medullary layer, with rather loose to ± dense texture, usually thin; hyphae somewhat horizontal to fairly vertical, irregularly interwoven, colorless, distinct or indistinct, slightly tortuous, 2.5-4 μm diam., thin- or slightly thick-walled. Hymenial layer distinctly thickening, constituting main part of basidiocarp, with rather compact texture; hyphae mainly vertical, colorless, ± agglutinated, slightly narrower than those of subiculum, thin-walled. Upper section near substratum usu-ally with two or three layers of abundant yellowish brown material, which dissolves rapidly in KOH. Cystidia numerous, immersed or projecting, overlapping in subhymenium, colorless, heavily encrusted in their apical halves, subulate, broadest in middle, basally narrow, 30-60 × 5.5-9.5 μm (encrustation excluded), with 0.8-2 μm thick walls, adventitious septa occasionally occur. Basidia narrowly clavate, 22-35 × 4-5 μm, 4-sterigmate. Basidiospores ellipsoid, adaxially flattened, smooth, thin-walled, 3.8-5.3 × 2.5-3 (-3.2) μm, IKI-, CB-.

 Note: This Basidiocarp of this species usually becomes purple in KOH; this, together with the thin subiculum and the yellowish brown layers in the basal subiculum, differentiates P. himalayensis from P. affinis.
