　Description： Basidiomata thin-resupinate, 30 to 50 µm thick, fresh whitish to pale cream, dry transparent, very inconspicuous. Hyphae thin-walled, 0.5-1.5 µm in diameter, hyaline, slightly tortuous, embedded in a gelatinous matrix. Hyphidia scattered, developing from subhymenial hyphae, clamped, tortuous and apically branched, growing into the hymenium and interspersed with basidia and gloeocystidia. Gloeocystidia inconspicuous, developing laterally from basal hyphae, thin-walled at maturity, short-cylindrical, 15-30 × 8-12 µm. Basidia obovoid, pyriform or stout clavate 15-25 × 8-12 µm, stalked, stalks up to 10 µm long, mature apically shortly longitudinally cruciate-septate; sterigmata thick, basally swollen, 2-3.5 µm in diam., up to 12 µm long; occasionally basidial development of the Repetobasidium-type. Basidiospores short-cylindrical, 10-11 × 5 µm, smooth, hyaline, nonamyloid, only germination by repetition observed.

　Note： Heterorepetobasidium ellipsoideum is characterized by its elliptical spores and inconspicuous, mature thin-walled gloeocystidia, thus clearly distinguishable from H. ellip-soideum.
