Witch's Butter

Gelatinous yellow-orange fruiting bodies that resemble orange marmalade smeared all over a branch. The fruiting bodies are composed of brain-like sections/lobes and have no stems. They feel like gummy bears and are surprisingly tough.

This fungus grows on the dead wood of many types of trees, but it is particularly common of birch. However, it's not the wood that Tremella mesenterica feeds upon, but rather the crust fungi, which have been feeding on the wood. Therefore, this fungus is more parasitic than it is saprobic.
