Tremella mesenterica Retzius (1769)
Tremella mesenterica grows from debarked dead hardwoods. It is a 'Witches Butter’ that parasitizes the mycelium of the crust fungus, Peniophora. The similar-looking Dacrymyces chrysospermus (Dacrymyces palmatus) grows on debarked conifers and has a white mycelial attachment point. Tremella mesenterica is an edible fungus that differs from Tremella aurantia in having glossier lobed globs or fans than the latter. Unlike Tremella aurantia, which is parasitic on mycelium of Stereum, Tremella mesenterica is parasitic on species of fungi in the Peniophoraceae family.
