Lifespan
1–2 years
Diet
Parasitic on mycelium of other wood-rotting fungi, particularly Annulohypoxylon species.
Habitat

Range
Throughout North Island and northern South Island on dead wood in humid, lowland areas.
Endemism
Introduced
Main Threats
No significant conservation threats identified. Removal of dead wood reduces available substrate.
Population
White, gelatinous fungus on dead wood, parasitising other wood-rotting fungi. Rehydrates when wet.

Te Ao Māori
In Chinese culture, Jelly Fungus is known as silver ear. It is a delicacy used in soups and desserts. In New Zealand, it has no traditional Māori significance. It is an introduced species. For foragers, it is a tasty find. It represents a little piece of Asia in local forests. The cultural connection is imported rather than indigenous. The culinary use drives interest. The lack of Māori naming reflects its recent arrival. It exists outside traditional frameworks. The foraging community values it. The texture is the primary appeal. The cultural layer is thin but specific. It connects local ecology to global cuisine. The fungus bridges this gap. It is a guest that stayed. The acceptance is practical. The taste is the justification.
The shape-shifter of the forest floor. A fungus that turns from crust to jelly. Tremella fuciformis is a white, translucent, gelatinous mass. It measures two to ten centimetres across. The surface is convoluted and brain-like. It has no distinct cap or stem. It is a soft, wobbly blob. It looks like it belongs in the ocean. Instead, it sits on a dead branch in the forest. The context is unexpected. The appearance is alien. When touched, it is soft. It is squishy and slightly slippery. It resembles a jellyfish or a piece of wet silicone. It wobbles when poked. It tears easily. This fragility is notable. When it is dry, the transformation is complete. It shrivels to a hard, brittle crust. It looks like nothing at all. It becomes invisible. When it rains, it rehydrates. It expands. It returns to its full, jelly-like form in a matter of hours. The speed is impressive. The mechanism is efficient. This fungus is a parasite, not a saprotroph. Jelly fungus does not feed on wood directly. Instead, it grows on the mycelium of other wood-rotting fungi. It targets Annulohypoxylon species particularly. It hijacks the host's mycelium. It steals the nutrients that the host has extracted from the dead wood. It is a fungal vampire. It is a thief in the dark. The relationship is one-sided. The host does not benefit. The jelly fungus takes what it needs. It operates without permission. Edible. In China, jelly fungus is cultivated. It is sold as silver ear or snow fungus. It is used in soups and desserts for its unique texture. It is said to be good for the skin. It is said to be good for the lungs. It is said to be good for the immune system. The culinary value is high. The medicinal claims are persistent. The demand is global. To find jelly fungus is to find a piece of Asian cuisine growing on a New Zealand branch. The dead branch is damp. The jelly fungus is a wobbly, translucent blob. It is brain-like and soft. It is dry. It shrivels to a crust. It rains. It expands back to jelly. It does not know it is a shape-shifter. It does not know it is edible. It simply exists in this state. The cycle repeats. It just wants to steal nutrients. The world is connected. Fungi travel with people. The forest is never static. It is always absorbing new arrivals. The jelly fungus is proof of this movement. It arrived from elsewhere. It established itself here. It thrives in the damp conditions. It exploits the local fungi. The integration is seamless. The origin is foreign. The presence is now native. No one told it otherwise.
