　Description： Macroscopic characters: Basidiocarps resupinate, widely effused, adnate, 230–300 μm thick, 10 × 20 cm, ceraceous, even, distinctly finely cracked, light buff, cream color to maize yellow, turning olive-buff color in 5% KOH (also the barks of Taiwan red pine); margins thining out, pruinose, concolorous or white. Microscopic characters: Basal layer of context almost none; the basal part of the intermediate layer with densely interwoven distinct hyphae, occupied about one half of the thickness of the context 100 μm thick; the upper part of intermediate layer of context 100–170 μm thick, composed of longitudinally interwoven gelatinized obscure hyphae; hyphae 2.5–3–(5) μm wide, with rare clamp connections, thin-walled, smooth; cystidia irregularly swollen in long spindle shape and narrowly cylindrical at upper part, rounded at apex, sometimes encrusted at tips, 5–9 × 20–45 μm, mostly with narrower tube-like upper parts in the width of 2.5 μm, with the crystals dissolved in KOH, confined to the hymenial layer, protruding 15–20 μm high; hymenial layer 25 μm thick, with the elements arranged in palisade; basidia subclavate, 5.2–6 × 13–22 μm, with 3–4 basidiospores; sterigmata slender at tips, curved, 1.2–1.5 μm wide at base, 4.5–5 μm long; basidiospores ovate, broadly ellipsoid, 3–5 × 5–6.5 μm, smooth, thin-walled, apiculate, non-amyloid.

　Note： The new species is characterized by its having spindle shaped cystidia and their tips covered with crystals which are sometimes readily brocken off. Very closely related to Hyphodontia sambuci (Pers.) J. Erikss. in leptocystidia, hyphae, spores, but the new species can be separated from Hyphodontia sambuci by its macroscopic characters, i.e., thicker fruit bodies, maize yellow and turning olive-buff color in KOH solu-tion, and by its cystidia not capitate and sometimes encrusted at apical portions, and having densely interwoven hyphae at the base of the intermediate layer.
