About Tremella vesiculosa McNabb
Fruit bodies of Tremella vesiculosa are firm, gelatinous, and range in color from brick-red to reddish brown. They grow up to 5 cm (2 in) across, and have a lobed structure with thick, inflated (vesiculose) lobes. Microscopically, the basidia are tremelloid, meaning they are subglobose to broadly clavate with oblique to vertical septa. They are 4-celled and measure 11.5 to 20 by 8 to 12.5 μm. The basidiospores are smooth, ellipsoid, and measure 8 to 9 by 5.5 to 7 μm. Tremella vesiculosa acts as a parasite on lignicolous fungi, though its specific host species is not known. Original collections of the fungus were associated with xylariaceous fungi. It grows on dead, attached or fallen branches of broad-leaved trees. The species was first described from collections made in New Zealand, and has additionally been reported from Australia.
