　Description： Macroscopic characters: Basidiocarps resupinate, widely effused, strongly adnate, longitudinally spreading, 170–250 μm thick, 2.7–4×10–15 cm, ceraceous, even, felty in appearance, with reticulate ridges, finely linearly cracked, salmon-buff or seashell pink when fresh, light buff or cartridge buff when dry, not changing color or turning darker in 5% KOH; margins thining out, farinose, white, concolorous. Microscopic characters: Basal layer of context absent, or with a few parallel hyphae; intermediate layer of context composed of densely gelatinized interwoven hyphae, opaque, indistinct, embedded numerous encrusted hyphal pegs, yellowish brown at base or next to the substratum from which the hyphal pegs arising; hyphae 1.8–2.5 μm wide, thin-walled, smooth, with clamp connections found on the surface of exposed hyphal pegs from which the renewed hyphae occurred; hyphal pegs composed of parallel, compact slightly thick-walled, yellowish to yellowish brown hyphae, encrusted on the upper half, pine-tree-like, 37–50 μm wide at base, 50 μm long, with the individual fascicle hyphae 2–6.3 μm wide, 10–12 each hyphal peg in surface view or in longitudinal sections; hymenium 15 μm thick, with paraphyses and basidia arranged in dense palisade; basidia slender, clavate, 4–5 × 25 μm, with 4 basidiospores; sterigmata straight or slightly curved, 4-6 μm long; basidiospores narrowly ellipsoid, narrowly toward base, slightly flatten on one side, (2.3)–3–(3.2)×(3.5)–6–7.5–(8) μm, apiculate, sometimes attached with the upper part of the wilted sterigma, smooth, thin-walled, non-amyloid.

　Note： The collection from Orchid island is quite similar to the species, G. lineata Berk. et M.A. Curtis, widely distributed in the tropical areas of the world. Although our specimen has slight differences in spore size and thickness of the fruit bodies, we do not think it is neces-sary for us to establish a new taxon.
