　Description： Basidiocarp resupinate, effuse, fairly soft, adnate, submembranaceous (aculei membranaceous- subceraceous), 120-250 μm thick in section (aculei excluded). Hymenial surface hydnoid, aculei ivory yellow, whitish between aculei; margin whitish, thinning, byssoid. Aculei 5-7 per mm, separate, subulate, 80-120 μm wide, up to ca. 1 mm long. Hyphal system monomitic; hyphae nodose-septate. Subiculum fairly uniform, composed of medullary layer, with fairly loose texture; hyphae colorless, variously oriented, sparsely or moderately ramified, distinct, fairly straight, 2-3.5 μm diam., with 0.3-1 μm thick walls. Hymenial layer with dense texture; hyphae colorless, 1.5-2 μm diam., thin-walled. Trama with dense texture; hyphae colorless, mainly vertical, similar to those in subiculum. Gloeocystidia numerous, immersed or slightly emergent, colorless, long cylindrical or tubular, slightly flexuous, 3-8 μm diam, up to ca. 300 μm long, with 0.5-1.5 μm thick walls, SA－. Basidia clavate, 15-23 × 3-4 μm, 4-sterigmate. Basidiospores ellipsoid, adaxially slightly concave, aculeate (smooth in KOH), thin-walled, 2.7-3.3 × 2-2.4 μm, IKI bluish black, CB–.

　Note： Ginns (1986) critically studied all species referred to Dentipellis and accepted three species in this genus, viz. D. dissita (Berk. & Cooke) Maas G., D. fragilis (Pers.:Fr.) Donk, and D. leptodon (Mont.) Maas G.. Stalpers (1996) proposed a new combination, D. parmastoi (Nikol.) Stalpers, based on Amylodontia parmastoi Nikol. Dai (1998) further presented a species, D. microspora Y.C. Dai, based on two collections made from Changbaishan of NE China. Among Dentipellis, D. taiwaniana and D. microspora share the feature of small and similar-sized basidiospores. The latter species is distinguished from the former in having numerous dendrohyphidia in the hymenium, and this structure is lacking in the former. In addition, D. microspora occurs on gymnosperm wood of temperate region of NE China, while D. taiwaniana was found on angiosperm wood of subtropical lowland Taiwan. A key to the six known species of Dentipellis is given below.
