Microscopic:
spores 5.5-7 x 4.7-6 microns, nearly round to oval, thin-walled, lacking droplets, pale-blue-amyloid, apiculus 0.5-0.7 microns; basidia 4-spored, 20-25 x 7-8 microns, clavate, sterigmata 4 microns long; cystidia none or at the base of the fruitbody as sterile basidia; hyphae monomitic, 2-10 microns wide, cells up to 250 microns long, thin-walled, clamp connections present in the type; a similar collection found two days before in the same area had smaller spores 4-4.7 x 3.5-4 microns, narrower basidia 7-8 microns, tetrahedral crystals 10-22 microns long among the hyphae of the context, and no clamp connections
