 Description: Basidiocarps corticioid, very thin, opague, ca. 35-70 µm in thickness, flesh whitish gray reflection, dry hyaline to transparency film; dry inconspicuous film. Basidia without or with short to long stalks, probasidia clavate, 15-17 × 3-4 µm, mostly inconspicuous, thin- to slight thick-walled, metabasidia 45-95 × 5-6.5 µm, 4-spored on short sterigmata, 1-2 µm long; sacs mostly 20-25 × 6-7 µm, thin-walled, sometimes becoming enlargement when mature; paraphysis-like growing from under septum of sac, up to probasidia or longer; clampless; usually 2-3 sacks and basidia growing together from the same generative hypha. Basidiospores globose to subglobose, 8-10 × 7-9 µm, repetition, the secondary spores also globose to subglobose. Hyphae clampless, 3.5-6 µm in diameter, slight thick-walled at the basal part of basidiomata. Haustoria not detected.

 Note: Helicogloea globosa is similar to H. variabilis Wells in the shape of basidiospore but differs in dimension, sac measurement, and basidial morphology. Helicogloea lagerheimii, the most common species in the genus, is considered to be closely related but its basidio-spores are obviously larger than those of H. globosa. The new species is somewhat similar to H. sphaerospora (Möller) Baker in spore and sac morphology but lacks clamp connections. It differs from all other species with globose to oval basidiospores in dimension, basidial and hyphal morphology. Therefore, the new species is proposed.
