Basidia 4-spored, 20-25 x 6-7.5 µm. Cheilocystidia a mixture of clavate to vesiculose cells (30-45 x 18-20 µm) with a few ventricose cells 15-20 x 5-10 µm; pleurocystidia frequent, prominent, mucronate, lageniform or even ampulliform, 45-55 x 18-25 µm, sometimes with minute granulations at apex. Hymenophoral trama parallel with a few oleiferous hyphae. Pileipellis a palisadoderm of spheropedunculate cells 17-38 µm diam. Clamp-connections present.
