E-Flora BC: Electronic Atlas of the Flora of British Columbia

Summary:
Tremella globispora produces a small, whitish to light ocherish, soft, gelatinous fruitbody that is wrinkled or has brain-like markings, and hangs from the underside of s small twig like a colorless watery droplet. Growth starts in dead fruitbodies of pyrenomycetes, with emergence of the fruitbodies as small pustules.

It is found in BC (Ginns). It is "a commonly encountered species of jelly fungus in southwestern BC", and is also reported from the USA, France, Germany, and Czechoslovakia, (Brough), Switzerland (Breitenbach), and the United Kingdom (Reid).

Fruiting body:
0.4-0.5cm in diameter, by confluence reaching 1cm, hanging from undersides of small twigs as transparent-watery droplets, surface marked with cerebriform [brain-like] markings or wrinkles, on drying forming inconspicuous varnish-like film, (Reid), 0.2-0.5cm, irregularly hemispheric-pulvinate [hemispheric - cushion-shaped], "arising as dots from the openings made in the bark by the pyrenomycetes", upper surface with the spore-bearing surface tuberculate-undulating, deliquescing when old, flesh gelatinous, soft, when dry practically invisible; "whitish and opalescent to light ocherish, also sometimes discolored greenish by algae"; smooth, dull to shiny, (Breitenbach), at first tuberculate, up to (0.1)0.2-0.4(0.7)cm across, expanding and becoming irregularly pulvinate [cushion-shaped], and spreading across the surface, eventually becoming cerebriform [brain-like] or more often simply convoluted, with a maximum height of 0.1-0.2(0.5)cm, often coalescing with other fruitbodies to become (0.2)0.4-0.5(2)cm across, gelatinous when young but often becoming watery gelatinous when old or soaked for long periods; pale sordid translucent white, pinkish-white, or cream-color to yellow ("light cadmium", "cadmium yellow" or "mustard-yellow" (Ridgway colors)), (Brough), spore deposit white (Buczacki)

Microscopic:
spores 6-7.5 x 5-7 microns, nearly round to broadly oval, smooth, colorless, iodine stains the cytoplasm brown; hypobasidia 12-16 x 11-13 microns, nearly spherical, longitudinally (rarely transversely) septate, with 4 epibasidia; hyphae 1.5-4 microns wide, with granular contents, septa with clamp connections, some hyphae moniliform to catenulate, septa without clamp connections, according to Pilat breaking apart into individual components (conidia), (Breitenbach), spores (5)6.2-8.2(10.2) x 5.75-7.2(9.75) microns (from deposit, excluding the well-developed apiculus), nearly round, appearing slightly dorsiventrally compressed, thin-walled, colorless; basidia consisting of a globular head, 10-18 x 9-13 microns, which becomes divided into 4 segments by irregularly disposed oblique walls, and elongated stalk (from very short or lacking to 23 microns long), with a basal clamp connection, but without septum separating head from stalk; basidia arise at different levels and are at different stages of development; dikaryophyses absent; hyphae 2-3 microns wide, agglutinated, colorless, thin-walled, with clamp connections; the perithecia of the Diaporthe are often rather indistinct or ghost-like, and the Tremella fills and envelops them, (Reid), spores (6)7-9(10) x (6)7-9(10) microns, nearly round, one-celled, smooth, colorless, germination by budding or repetition; probasidia 20-40(150) x (10)12-16(20) microns, cruciate-septate with oblique septa, epibasidia cylindric, (1.5)2(3.5) microns wide, in some cases reaching over 100 microns in length; no visible penetration of hyphal strands of T. globospora through the walls of host perithecia, asci and ascospores left within the infected perithecia are infrequent, (Brough)
