Hyphoderma malenconii (Manjón & Moreno) Manjón, Moreno & Hjortstam, Mycotaxon 33: 261. 1988.

Basionym: Dendrothele malenconii Manjón & Moreno, Crypt. Mycol. 4: 147. 1983.

 Description: Basidiocarp effuse, adnate, membranaceous, 120-300 μm thick, in section. Hymenial surface Ivorly Yellow, Light Buff, or Pale Olive-Buff, smooth or slightly tuberculate, usually cracked when old; margin paler or concolorous, thinning, pruinose. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of basal layer, with compact texture, up to ca. 30 μm thick, sometimes indistinct; hyphae horizontal, colorless, fairly straight, agglutinated, 2.5-4 μm diam., thin- or slightly thick-walled. Hymenial surface with dense texture, distinctly thickening; hyphae ± vertical, colorless, somewhat agglutinated, indistinct, 2-3.5 μm diam., thin-walled. Crystal masses scattered in hymenial layer. Cystidia numerous, immersed, rarely slightly projecting, cylindrical, narrower towards the apices, irregularly flexuous, appically ± moniliform, 35-90 × 7-13 μm, thin-walled. Basidia utriform or subutriform, guttulate, 30-50 × 7-9 μm, normally 4-sterigmate. Basidiospores cylindrical, smooth, thin-walled, with small oil-drops or rather homogeneous contents, 12-15.5 (-17) × (4.5-) 5-6 μm, IKI-, CB-.

 Note: This species is characterized by the moniliform cystidia and the fairly large basidio-spores. To some extent it resembles Hyphoderma assimile (Jacks. & Deard.) Donk, whick has similary long but slightly narrower basidiospores, but the cystidia of H. assimile are normally cylindrical and not moniliform like those in H. malenconii.
