Fructifications tough-gelatinous, hyaline when young, becoming blackish brown at maturity, drying dull black. At first pustulate, anastomosing and becoming broadly effused, forming areas up to 18 cm in the longest dimension, surface sparsely or closely covered with sterile, wart-like papillae. Internal hyphae thin-walled, hyaline, l.5-5 µm diam., clamp connections present. Hymenium composed of dikaryophyses and basidia; dikaryophyses extending beyond the basidia, apices interwoven to form a tough, brown, agglutinated surface layer; probasidia obovate or elliptical, 10-18.5 x 8-15 µm, becoming longitudinally cruciate-septate; sterigmata cylindrical, to 30 µm long. Basidiospores allantoid, hyaline, apiculate, 10-16.5 x 4-5.5 µm

Exidia glandulosa is the commonest tremellaceous fungus in New Zealand, occurring on a wide range of hosts. It is not usual to find it on coniferous wood although it has been occasionally recorded on this substrate from Europe and North America.
In addition to E. glandulosa, which was first recorded from New Zealand by Colenso (1886, p. 306), a number of other Exidia species have been recorded from the country. E. albida Bref. was recorded by Massee (1906, p. 42) but no collection data were given. A specimen at Kew (Colenso no. bl5) filed under E. albida is a Tremella. It is too immature to permit specific identification but is possibly T. fuciformis Berk. Exidia nucleata (Schw.) Burt was recorded as Naematelia nucleata by both Colenso (1886. p. 306) and Massee (1906, p. 43). No collection data were given but two collections at Kew (Colenso, nos b93, b794) which macroscopically resemble Exidia nucleata proved to be the imperfect fungus Pleurocolla compressa (Ell. & Everh.) Diehl.
Lloyd (1925, p. 1356) described Exidia novo-zealandica from a Canterbury specimen. The type has not been examined but the description suggests that it is E. glandulosa.
E. glandulosa is characterised by dark, tough-gelatinous fructifications with sterile, wart-like papillae.
