C1/C2Specialist/Botanical/Mycological. Used in nature guides, scientific contexts, and by hobbyists.
Definition
Meaning
A type of fungus belonging to the class Tremellomycetes, characterized by a gelatinous, often brightly colored fruiting body that resembles jelly or rubber.
A broad common name for various basidiomycete fungi from several orders (e.g., Tremellales, Dacrymycetales) that produce fruiting bodies with a distinctively soft, gelatinous, or rubbery texture, especially when moist.
Linguistics
Semantic Notes
A compound noun where 'jelly' describes the texture and appearance, not edibility (though some species are edible). It is a hypernym for many specific genera (e.g., *Tremella*, *Auricularia*). Not to be confused with slime molds.

FAQ
Frequently Asked Questions
Some species are edible and used in Asian cuisine (e.g., *Auricularia* spp., wood ear), but many are not considered palatable or are of unknown edibility. Never eat a wild fungus without expert identification.
They typically grow on wood (logs, branches) or, in the case of parasitic species, on other fungi. They are most conspicuous during wet weather.
No, it is a descriptive common name for fungi from several different taxonomic orders that share a gelatinous physical form.
Identification requires noting substrate, colour, shape, time of year, and often microscopic features. A good field guide or app focused on fungi is essential.
