Basidiocarp resupinate, flat or cushion-like, ivory-white, up to ca. 4 × 2 cm, 1-5 mm thick, pores ca. 4 per mm; anamorphic marginal region with pale ochraceous bristles. Bristles scattered over surface of young basidiocarps of anamorphic stage. Hyphal system dimitic. Generative hyphae colorless, thin to thick-walled, with clamps, 2-4 μm diam.; skeletal hyphae fairly abundant, generally not branched, colorless, thick-walled, 2-6 μm diam. Cystidia of two kinds. The more frequent ones capitate, thin or thick-walled, 20-45 μm long, 7-8 μm diam. for terminal swelling parts; encrusted cystidia rare, subulate, thick-walled, ca. 20 × 5 μm. Basidia with basal clamps, cylindrical, slightly constricted at the middle, 14-16 × 4-5 μm, with four sterigmata. Basidiospores subglobose, with one oily drop when fresh, smooth, colorless, 4-5 × 3.8-4.3 μm, IKI–, CB–. Arthroconidia produced on the spines of the basidiocarps, in short chains, with or without basal clamp after detachment from the conidiogenous cells, colorless, thin-walled in culture, slightly thick-walled in dried material, ellipsoid or ovoid, 8-13 × 4-6 μm, IKI–, CB–.

Note：
The two species of Echinoporia can be distinguished by the sizes of pores, basidiospores, and conidia (Langer, 1994): Pores of E. hydnophora are smaller (3-5 pores/mm) than that of E. aculeifera (1-3 pores/mm), whereas basidiospores are larger in E. hydnophora (5-5.5 × 4.5-5 μm) compared to those of E. aculeifera (4-5 × 3-3.5 μm). Ryvarden and Johansen (1980) measured basidiospores of E. hydnophora as 4-5 μm diam., more fitting those of this study. E. aculeifera is restricted to the neotropical region and E. hydnophora to the palaeotropical region (Gilbertson and Ryvarden, 1986). The finding of E. hydnophora in Taiwan represents the northern-most known population of this species. Gilbertson and Ryvarden (1986) and Ryvarden (1991) considered the hyphal system of species of Echinoporia very similar to that of species of Hyphodontia. The hypothesis of close relationship between these two genera was supported by parsimony analyses of morphological data and ultrastructural studies by Langer (1994). Both Hyphodontia spp. and E. aculeifera have dolipores with continuous parenthesomes (Langer, 1994).
