Tremella vesiculosa is a species of fungus in the family Tremellaceae. It produces light brown, lobed, gelatinous basidiocarps (fruit bodies) and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from New Zealand.

Taxonomy

[edit]

Tremella vesiculosa was first published in 1990 by Robert Bandoni and Peter Buchanan, based on collections and notes made by the late New Zealand mycologist R.F.R. McNabb.[1]

Description

[edit]

Fruit bodies are firm, gelatinous, brick-red to reddish brown, up to 5 cm (2 in) across, and lobed, the lobes thick and inflated (vesiculose). Microscopically, the basidia are tremelloid (subglobose to broadly clavate, with oblique to vertical septa), 4-celled, 11.5 to 20 by 8 to 12.5 μm. The basidiospores are ellipsoid, smooth, 8 to 9 by 5.5 to 7 μm.[1]

Similar species

[edit]

Phaeotremella species are both brown and gelatinous, but have lobes that are comparatively thin, uninflated, and frondose. Tremella laurisilvae, described from the Canary Islands, is similar but geographically distant.[2]

Habitat and distribution

[edit]

Tremella vesiculosa is a parasite on lignicolous fungi, but its host species is unknown, though the original collections were associated with xylariaceous fungi. It is found on dead, attached or fallen branches of broad-leaved trees.[1]

The species was described from New Zealand and has been reported from Australia.
