Witches Butter Tremella mesenterica (Schaeffer) Retx.    Synonyms: Tremella lutescens, Witch's Butter.
Kingdom Fungi   >   Phylum Basidiomycota   >   Class Tremellomycetes   >   Order Tremellales   >   Family Tremellaceae   >   Genus Tremella   

Status:

Found in clusters on decaying hardwoods.

Description:

Fruiting body: Yellow to yellow-orange; rubbery, wrinkled, gelatinous, mass. Identifying the substrate is essential. This species grows on hardwoods, while the similar Orange Jelly (Dacrymyces palmatus) grows on conifers.

Relationships:

Parasitizes Giraffe Spots and other members of the genus Peniophora. Because the Witches Butter fruiting bodies arise from the Peniophora mycelium, only infrequently are the fruiting bodies of the two visible at the same time. (J. Solem, pers. comm.)
