　Description： Basidiocarp resupinate, effuse, adnate, membranaceous, 200-500 μm thick in section. Hymenial surface light cream-colored, ± reddening in KOH, smooth, occasionally cracked; margin of an immature zone, sulfuric yellow, with distinct marginal cordons which extend several centimeters long. Hyphal system monomitic; hyphae mostly simple-septate, rarely clamped. Subiculum composed of a medullary layer, with somewhat loose to fairly dense texture; hyphae colorless, ± horizontal, 3-6 μm diam., with 0.5-1.5 μm thick walls, abundantly covered with crystal granules. Hymenium thickening, with dense texture; hyphae colorless, slightly thick-walled. Lamprocystidia numerous, immersed or projecting, usually overlapping in the subhymenium, conical, subsubulate, or cylindrical, apically heavily encrusted, colorless, 20-50 × 7-12 μm (with encrustation), with 0.5-1 μm thick walls. Basidia clavate, 20-30 × 5-6 μm, 4-sterigmate. Basidiospores broadly ellipsoid, adaxially ± flattened, smooth, thin-walled, 3.7-5 × 2.8-3.3 μm, IKI-, CB-.

　Note： Phanerochaete rubescens is allied to P. salmoneolutea Burds. & Gilb. in having the features of marginal cordons, red color-change of the hymenial surface in KOH, the pres-ence of lamprocystidia, and similar size of basidiospores. However, the former species has orange hymenial surface, thin-walled lamprocystidia, and has slightly longer basidiospores. Phanerochaete subiculosa (Burt) Burds., another similar species, has a hymenial surface color which does not change in KOH, slightly longer basidiospores, and grows on conifer-ous wood (Burdsall, 1985).
