Subiculum uniform, composed of basal layer, with compact texture, thin, up to ca. 20 μm thick; hyphae horizontal, colorless, rather distinct, ± agglutinated, straight, 3-6 μm diam., thin- or slightly thick-walled. Hymenial layer with compact texture, distinctly thickening; hyphae ± vertical, colorless, usually agglutinated, indistinct, 2-3.5 μm diam., thin-walled. Crystals and yellow resinous material rather common throughout section.
