 The spores are spindle-shaped to elliptical, have a smooth surface, and dimensions of 8–11 to 3–4 µm.There are both two- and four-spored basidia (spore-bearing cells), and they are club-shaped, hyaline (translucent), with dimensions of 28–36 by 10–12 µm.Cystidia are plentiful, and are found in bundles lined along the tube mouths (as cheilocystidia), or more commonly, singly along the sides of the tubes (as pleurocystidia).
