spores 3.5-5 x 1-1.5 microns, cylindric, somewhat allantoid (curved), smooth, inamyloid, colorless; basidia 4-spored, 10-13 x 4-5 microns, clavate, with basal clamp; cystidia frequent to rare, completely imbedded or projecting to 40 microns, 40-70 x 9-11 microns, clavate, partly to completely incrusted, thick-walled, hyphal pegs usually present; hyphal system dimitic, subicular generative hyphae mostly 2-6 microns wide, some near substrate up to 8 microns wide, "thin-walled, rarely branched, with clamps", subicular skeletal hyphae 2-6 microns wide, colorless, "thick-walled, non-septate, with rare branching", trama hyphae similar
