 Description: Basidiocarp resupinate, effuse, adnate, subceraceous, 30-100 μm thick in section. Hymenial surface pale yellow to yellowish white, smooth, extensively cracked; margin concolorous, thinning, pruinose. Hyphal system monomitic; hyphae nodose-septate. Subiculum fairly uniform, thin and sometimes indistinct, with compact texture; hyphae mainly horizontal, colorless, sometimes indistinct, 1.7-4 μm diam., with fairly thin to ca. 1 μm thick walls. Hymenial layer thin or indistinct, not clearly differentiated from subiculum. Gloeocystidia numerous, emergent or immersed, mostly colorless, cylindrical, sometimes slightly flexuous, apically obtuse, 20-55 × 8-12 μm, with 0.5-2 μm thick walls, SA+. Basidia utriform or suburniform, 22-35 × 6-7 μm, 4-sterigmate. Basidiospores cylindrical, indistinctly verrucose or seemingly smooth, thin-walled, (11-) 11.5-13.5 (-14) × 4-5.2 (-5.8) μm, IKI bluish black, CB–.

 Note: This species is characterized by the large basidia and basidiospores, the latter cylindrical and indistinctly ornamented. Most Boidinia species have fairly small basidiospores, which are globose to broadly ellipsoid in shape and fairly distinctly ornamented. This species is also distinct in having homothallic sexuality and holodikaryotic nuclear behavior, this species is rather atypical in the genus Boidinia.
