Tremella fuciformis Fruiting Body Identity
The botanical entity is Tremella fuciformis Berk., a jelly fungus that belongs to the order Tremellales and is sold as snow fungus or silver ear. The part used is the dried fruiting body. Mycelium, culture substrate and spores are not part of this Tremella mushroom extract. Golden ear, Tremella aurantialba, is a different species with an orange color, and wood ear, Auricularia, is an unrelated black jelly fungus, so the species name is the only safe separator in quotes.
Cultivated snow fungus grows together with a companion fungus on wood or sawdust substrate. The fruiting body is rich in acidic heteropolysaccharides built on a mannan backbone, which bind large amounts of water and form viscous gels.
For label and specification work, the species name together with the fruiting body is the identity to quote.
