Hyphodontia tubuliformis Sheng H. Wu, Mycotaxon 95: 185. 2006..

 Description: Basidiocarp resupinate, effuse, submembranaceous-pellicular, fairly soft, 70-200 μm thick in section (aculei excluded). Hymenial surface cream, grandinioid-odontioid, not cracking; margin thinning out, arachnoid, concolorous. Aculei separate or fused, > 10 per mm, conical or subulate, up to ca. 120 μm long and 60 μm wide.Hyphal system monomitic; hyphae nodose-septate. Subiculum with fairly loose texture; hyphae moderately ramified, colorless, ± vertically oriented, distinct and fairly straight, 2.5-4.5 μm diam., hyphal walls from slightly thickened to 1.2 μm thick. Hymenium somewhat thickening, with dense texture; hyphae colorless, much narrower than those of subiculum, thin-walled. Cystidia numerous, more concentrated in aculei, scattered elsewhere, usually projecting, arising from subiculum, tubular, sometimes slightly constricted near apices, colorless, 40-200 x 5-8 μm, thick-walled (0.5-2.5 μm thick) except for the thin-walled apex. Basidia suburniform, 7-13 x 3.3-4 μm, 4-sterigmate. Basidiospores cylindrical, adaxially slightly concave, smooth, thin-walled, 4.7-5.5 × 1.8-2.2 μm, IKI–, CB–.

 Note: Hyphodontia tubuliformis is similar to Hyphodontia microspora J. Erikss..& Hjortstam, but has longer basidiospores. The spore measurements for H. microspora were respectively given as 2.5-3.5 × 1.5-1.8 μm (Eriksson & Ryvarden 1976), 3.8-4.5 × 1.8-2.2 μm (Wu 1990), 3.7-4.3 × 1.8-2.1 μm (holotype, Wu 1990) and 2.5-4.5 × 1.5-2.5 μm (Langer 1994).
