Phanerochaete leptoderma Sheng H. Wu, Acta Bot. Fennica 142: 45. 1990.

 Description: Basidiocarp effuse, adnate, pulverulent, subceraceous when old, 100-220 µm thick in section. Hymenial surface whidsh or Cream Color, no color changes in KOH, smooth, sometimes slightly pilose due to projecting cystidia, rarely cracked; margin concolorous or paler, slightly arachnoid-filamentose. Hyphal system monomitic; hyphae simple-septate. Subiculum uniform, composed of medullary layer, with compact or rather compact texture, 10-50 µm thick; hyphae horizontal, somewhat vertical near subhymenium, colorless, rather distinct, straight, ± agglutinated, 2.5-4.5 µm diam., thin- or slightly thick-walled; hymenial layer with rather dense texture near subiculum, compact next to hymenium, thickening; hyphae ±vertical, colorless, distinct or indistinct, sometimes slightly tortuous, 2-4 µm diam., thin-walled, sometimes encrusted with a thin layer of crystals, anastomoses occasional. Cys-tidia variably abundant, immersed or projecting for approximately half their lengths, sometimes overlapping in thickening subhymenium, colorless, cylindrical with narrower apices, apically obtuse or acute, apical halves encrusted with thin layer of crystals, which gradually dissolve in KOH, 35-65 × 4-6 µm (encrustation excluded), with 0.5-1.2 µm thick walls, adventitious septa occasionally occur. Basidia clavate or subclavate, 21-28 ×4.7-6 µm, 4-sterigmate. Basidiospores cylindrical, smooth, thin-walled, usually with several small oil-drops, (6.2-) 6.4-7.6 (-8) × 2.9-3.3 µm, IKI-, CB-.

 Note: This species sometimes exhibits overlapping cystidia in its thickening subhymenium, a character shared with Phanerochaete laevis, from which it differs in having narrower and thinner-walled subicular hyphae, and longer but narrower basidiospores.
