Tremella mesenterica
The yellow brain is a jelly fungus with a gelatinous, orange-yellow fruit body up to 7.5 cm across and a convoluted or lobed surface that is greasy when damp. It is a parasite of wood-decay fungi in the genus Peniophora.
Found in deciduous and mixed forests on dead but attached and recently fallen branches, appearing in bark crevices during rainy weather.
Widely distributed in temperate and tropical regions of Africa, Asia, Australia, Europe and the Americas.
Identification suggestions (from the community or from AI) and the information here may be wrong; this app never confirms that anything is safe to eat. Do not consume wild plants, mushrooms or seafood without expert confirmation. Nothing here is medical advice.
It dries into a thin film after rain and revives after the next shower.
Never eat a wild mushroom without showing it to an expert
No mushroom should be picked for eating based on this app or a photo. Deadly species look very like the ones foragers look for, and symptoms start hours later. If you suspect poisoning, call your local poison centre or emergency number right away (in Türkiye: 114).
