 The spores are smooth, thin-walled, and hyaline (translucent).They are allantoid (long with rounded ends) to ovoid (egg-shaped), and are non-reactive with Melzer's reagent.There are no cystidia in the hymenium, although there may be cystidioles (sterile cells of about the same diameter and shape as an immature basidium that protrude beyond the surface of the hymenium).
