Microscopic:
SPORES 6-8 x 4-5 microns, elliptic, smooth, inamyloid, acyanophilic, thin-walled; BASIDIA 4-spored, 9-12 x 5-6 microns, subglobose-pyriform, with basal clamp connection, subbasidial stem reaching 50 microns; CYSTIDIA "35-45 x 4-6 microns, cylindrical or somewhat tapering, capitate with an excreted globule, in the dry state composed of a grainy yellow - red substance; globules easily seen under the lens (50 x) as gold or amber-colored pearls; in the basal part of the cystidium normally one clamp"; HYPHAE monomitic: "hyphae 3-4 microns wide, with clamps, basal hyphae forming a sparse net on the wood, with short perpendicular hymenial branches", (Eriksson)
