Description: | Basidiocarp resupinate, effuse, adnate, porous-reticulate when young, membranaceous or subceraceous when old, 50-300 μm thick in section (dissepiments excluded). Hymenial surface cream, poroid when young, but the dissepiments soon become split; margin paler in color, thinning, pruinose-arachnoid. Pores angular or round, 4-6 per mm; tube layer 100-350 μm deep, dissepiments 60-150 μm thick. Hyphal system monomitic; hyphae nodose-septate. Basal layer usually very thin or lacking. Context with moderately loose to fairly dense texture; hyphae colorless, vertical, fairly distinct and straight, moderately ramified, 2-4 μm diam., with thin to ca 1.2 μm thick walls. Trama with compact texture; hyphae yellowish and fairly vertical. Subhymenium slightly thickening, not clearly differentiated. Capitate cystidial elements numerous, present in subiculum and hymenial layer, colorless, apically covered with yellowish resinous materials, 10-45 × 3.5-5 μm (resinous materials excluded), thin- or slightly thick-walled. Basidia suburniform, 14-20 × 4-5 μm, 4-sterigmate. Basidial elements brownish in IKI. Basidiospores narrowly ellipsoid, adaxially slightly concave or flattened, smooth, thin-walled, with one distinct oil-drop, 4.5-5.5 × 2.6-3 μm, IKI–, CB–. | |||

Note: | Hyphodontia taiwaniana has narrower basidiospores than H. niemelaei. This species is also reminiscent of H. flavipora but has slightly longer and narrower basidiospores. Among the three studied specimens, Wu 9312-65 has almost all hyphae thin-walled, representative of typical generative hyphae. Holotype and Wu 9912-3 have thin- to thick-walled hyphae. The clamped septa are more difficult to find on thick-walled hyphae. | |||
