Tremella fuciformis

Snow fungus

A translucent white jelly fungus that parasitises Annulohypoxylon wood-decay fungi on dead broadleaf branches. It is a major cultivated food and tonic in East Asia, grown by co-inoculating sawdust with both Tremella and its host. It needs warm, very humid, well-aired conditions to fruit.

Where it grows wild

Dead attached or fallen branches of broadleaf trees, where it grows on the mycelium of Annulohypoxylon (formerly Hypoxylon) rather than on the wood itself. It exists as a yeast until it meets its host.

Mostly lowland. Recorded elevations span 0–2000 m, median 318 m (41 records).
