Hymenium thickening, differentiated from subiculum, with compact texture; hyphae mainly vertical, somewhat yellow, glued together and indistinct, ca. 2 μm diam., with thickened walls. Gloeocystidia emergent or immersed, colorless or yellowish, cylindrical or ±fusiform, quite often apically with a schizopapillate constriction, 30-100 × 5-10 μm, with thin or slightly thickened walls, SA+. Basidia clavate, 20-24 × 5-6 μm, with thickened walls at least for the basal parts, 4-sterigmate.
