Hyphoderma allantosporum Sheng H. Wu, Acta Bot. Fennica 142: 65. 1990.

 Description: Basidiocarp effuse, adnate, membranaceous, 40-150 µm thick in section. Hymenial surface Deep Olive-Buff, Pale Olive-Buff, or Ivory Yellow, smooth, extensively cracked; margin concolorous or paler, rather determinate, sometimes slightly arachnoid. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, mainly composed of basal layer, with compact texture, up to ca. 12 µm thick, sometimes indistinct; hyphae horizontal, colorless, straight, agglutinated, 2.5-3.5 µm diam., thin- or slightly thick-walled. Hymenial layer with ± dense texture, thickening; hyphae ± vertical, colorless, ± agglutinated, indistinct, somewhat tortuous, 1.8-3.5 µm diam., thin-walled. Cystidia numerous, slightly projecting or immersed, subulate or fusiform, slightly flexuous, sometimes containing yellow resinous inclusions, 25-50 × 8.5-12.5 µm, thin-walled. Basidia subutriform or subclavate, usually guttulate, 17-27 × 7-8.5 µm, 4-sterigmate. Basidiospores allantoid, smooth, thin-walled, with oil-drops, (10.5-) 11-13 (-14) × 3.3-4.2 µm, IKI-, CB-.

 Note: The cystidia of this species are similar to those of Hyphoderma pallidum (Bres.) Donk and H. tsugae (Burt) J. Erikss. & Strid., but has longer basidiopsores and lacks the capitate hyphal ends.
