Spores 7-9.5 × 7-8 µ; subglobose; ornamentation 1.5-2.5 µ high, as amyloid spines and wide, branched ridges that do not generally form reticula. Pleuromacrocystidia absent. Cheilocystidia subcylindric; to about 35 × 5 µ. Pileipellis a trichoepithelium or trichopalisade, with terminal cells cylindric to subclavate.
