 Description: Macroscopic characters: Basidiocarps resupinate, widely effused, adnate, 40–175 μm thick, 1–3 × 10–20 cm, membranaceous or arachnoid, even, or slightly warted by compact hyphae in fascicles when protruding, 25 μm high, 20 μm wide at base, not cracked, yellowish green, yellow to whitish yellow, turning deep violet in 5% KOH when fresh, and turning black violet when dry; margins thining out, concolorous, with mycelial strands, up to 0.5–1 mm in diam. Microscopic characters: Basal layer 20–25 μm thick, composed of parallel gelatinized hyphae; intermediate layer 20–150 μm thick, composed of longitudinally loosely interwoven hyphae, with yellow granules deposited, often conglutinized when dry; hyphae 2–5 μm wide (2–7 μm wide in mycelial strands), thin-walled, smooth or finely encrusted, septate or with large clamp connections; cystidia (gloeocystidia) capitate, embedded abundantly, readily stained by phloxine, 8–12 μm in diameter at globose or obpyriform head, 5–9 μm wide at pedicels, thin-walled, smooth; hymenium 15 μm thick; basidia cucurbitiform, ventricose, 4 × 12 μm, with 2–4 basidiospores; sterigmata 5 μm long; basidiospores ovoid, elliptic, 2–2.3 × 3.2–4.5 μm, smooth, thin-walled, non-amyloid.

 Note: This species is characterized by yellowish green hymenophores which apparently turn to deep violet in 5% KOH solution and is usually accompanied by bright yellow mycelium in faveola. Microscopically it posses cucurbitiform or ventricose basidia, capitate cystidia (gloeocystidia) and the distinguished hyphae which have large peculiar clamp connections from which a lateral hyphal branch always occurs and some of which are coated with fine crystals. It is closely allied to Odontia wrightii (Berk. et Curt.) Burt, but the latter has well-defined teeth, while the Phlebia chrysocrea has the surface even or slightly warted. Phlebia livida (Pers. ex Fr.) Bres. is also readily confused with P. chrysocrea, however, the former can be distinguished from the latter by its pinkish-buff to bluish-gray color and thick-walled, long-celled hyphae. Additionally, Phlebia chrysocrea occurs exclusively on hardwoods, while P. livida seems to grow only on softwoods.
