Tremella tremelloides
species of fungi in the genus Tremella
Tremella tremelloides is a species of fungus in the order Tremellales. It produces yellowish, brain-like to densely lobed, gelatinous basidiocarps (fruit bodies) and is parasitic on Stereum basidiocarps on dead branches of broadleaved trees. It was originally described from the USA.
Taxonomy
The species was first published in 1873 by British mycologist Miles Joseph Berkeley who placed it in the genus Sparassis, interpreting the lobes as compacted branches. It was subsequently transferred to Tremella by George Edward Massee in 1889. American mycologist Robert Joseph Bandoni restudied collections in 1961, placing Naematelia quercina in synonymy and noting a similarity between Tremella tremelloides on broadleaf trees and Naematelia encephala on conifers. As a parasite of Stereum fruit bodies, Tremella tremelloides belongs in the genus Naematelia, but the species has not as yet undergone DNA sequencing to confirm this.
Description
Fruit bodies are gelatinous, hemispherical at first becoming lobed, the lobes often flattened and compact, yellowish, with a denser whitish core when sectioned. Microscopically, the hyphae have clamp connections. The basidia are tremelloid (globose to subglobose, with oblique to vertical septa) and unstalked, 4-celled, 14 to 22 by 12 to 18 μm. The basidiospores are subglobose, smooth, 9 to 12 by 9 to 11 μm.
This brief starts where responsible research should: with the source description of “Tremella tremelloides” as species of fungi in the genus Tremella. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of fungi in the genus Tremella. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 8, 2025. The linked authority identifier is Q108440479. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1873, 1889 and 1961.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
