Microscopic: spores 5.5-8 x 5-6(7.5) microns, nearly round to elliptic, with a distinct apiculus; basidia "when mature, 1-septate, not constricted at the septum, septum longitudinal, oblique or transverse", 11-20 x 7.5-10 microns, epibasidia 20-26 x 2-3.5 microns, subcylindric; hymenium colorless, containing numerous probasidia, probasidial initials elliptic, proliferations occurring through the basal clamp connection; hyphidia and cystidia absent; hyphae of context 1-2 microns wide, thin-walled, clamp connections not seen; haustorial branches present but rare, mother cell ellipsoid, 3-4 x 2.5-3 microns, haustorial filament 2-11 x 0.5 microns; anamorph unknown
