     This yellow jelly fungus, commonly known as Witch's Butter, is seen only during the rainy season.

     Auricularia (jelly fungi) was placed within Hymenomycetes in the gene trees, which showed that the split between Urediniomycetes and Hymenomycetes occurred long before the split between jelly fungi and mushrooms.

   • 2010, Michael Kuo; Andy Methven, 100 Cool Mushrooms, page 185:

     Tremella fuciformis is a tropical and subtropical jelly fungus found on hardwood logs after heavy rains. It is whitish or nearly transparent, and fairly large (up to 7 cm across)—and it features graceful gelatinous lobes rather than the glob-like blobs that typify so many other jelly fungi.

Jelly fungi were formerly included in the (now obsolete) paraphyletic grouping Heterobasidiomycetes, but are now spread among several orders: Tremellales, Dacrymycetales, Auriculariales, and Sebacinales. The grouping Heterobasidiomycetes is still used informally.
