　Description： Basidiocarp resupinate, effuse, adnate, membranaceous, 80-200 μm thick in section. Hymenial surface pale yellow to yellowish white, smooth, occasionally cracked; margin thinning, paler, arachnoid-pruinose. Hyphal system monomitic; hyphae nodose-septate. Subiculum fairly uniform, composed of a thin basal layer, with dense texture; hyphae horizontal, colorless, 2-3.5 μm diam., thin-walled, with numerous small oil-drops. Hymenium thickening, differentiated from subiculum; hyphae ± vertical, colorless, 1.5-3 μm diam., thin-walled, with numerous small oil-drops. Gloeocystidia numerous, usually immersed, cylindrical, ±flexuous, usually schizopapillate toward apices, colorless, 5-10 μm diam., up to 120 μm long, thin- or slightly thick-walled, SA+ (turning purple) when fresh, but SA– 5 months after collection. Basidia clavate, 15-25 × 3.5-4 μm, 4-sterigmate. Basidiospores subglobose, verrucose (smooth in KOH), thin-walled, 3.8-4.3 × 2.9-3.4 μm, IKI bluish black, CB–.

　Note： This new species is similar to Gloeocystidiellum kenyense Hjortst. but the latter has smaller basidiospores (3-3.8 × 2.3-2.8 μm, measured from holotype: Ryv. 8996 at O). Gloeocystidia of G. purpureum turn purple in SA, a peculiar color change for species in the genus.
