　Description： Basidiocarp effuse, adnate, subceraceous, 50-150 μm thick in section (aculei excluded). Hymenial surface Light Buff, odontioid, not cracked; margin paler, thinning, arachnoid. Aculei usually separate, ca. 3 per mm, subulate with obtuse apices, apically encrusted with brownish resinous material, 250-500 × 100-200 μm. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of medullary layer, with rather dense texture; hyphae richly ramified and densely interwoven, slightly yellowish, rather tortuous near subhymenium, indistinct, 2-4 (-4.8) μm diam., with 0.7-1.5 μm thick walls. Subhymenium somewhat differentiated, with compact texture; hyphae colorless, strongly tortuous and interwoven, narrower and with thinner walls than those of subiculum. Cystidia numerous, of palisade arrangement in trama, immersed or projecting, colorless, tubular, often longer than 150 μm, 2.5-5 μm diam., thin- or slightly thick-walled, adventitious septa numerous. Yellowish resinous material abundant within aculei, dissolving in KOH. Basidia narrowly clavate, 14-19 × 2.2-2.8 μm, 4-sterigmate. Basidiospores allantoid, smooth, thin-walled, usually with several oil-drops, (4.2-) 4.5-6 (-6.3) × 1-1.4 μm, IKI-, CB-.

　Note： Hjortstam (1983b) and Hjorstam & Bononi (1987) reported that the East African and Brazilizn specimens have a more distinctly odontioid hymenial surface than the European collections. The Taiwanian collection was made in subtropical Taiwan, but it is not sure whether it belongs to the East African and Brazilian type. It lacks the “hymenial cystidia” described by Eriksson and Ryvarden (1975: 347), and the basidia are shorter than in their descriptions of the species.
